    Abstract

    In 1637 Fermat wrote: “It is impossible to separate a cube into two cubes, or a biquadrate into two biquadrates, or in general any power higher than the second into powers of like degree: I have discovered a truly marvelous proof, which this margin is too small to contain.”

    This means: ( 2)n n nx y z n+ = > has no integer solutions, all different from 0(i.e., it has only the trivial solution, where one of the integers is equal to 0). It has been called Fermat’s last

    theorem (FLT). It suffices to prove FLT for exponent 4. and every prime exponent P . Fermat proved FLT for exponent 4. Euler proved FLT for exponent 3.

    In this paper using automorphic functions we prove FLT for exponents 6P and P , where P is an odd prime. The proof of FLT must be direct .But indirect proof of FLT is disbelieving.

    In 1974 Jiang found out Euler formula of the cyclotomic real numbers in the cyclotomic

    Euler prove that (15) has no rational solutions for exponent 3[8]. Therefore we prove that (18) has no rational solutions for prime exponent P [5,7]. Remark. It suffices to prove FLT for exponent 4. Let Pn 4= , where P is an odd prime. We have the Fermat’s equation for exponent P4 and the Fermat’s equation for exponent P [2,5,7]. This is the proof that Fermat thought to have had. In complex hyperbolic functions let exponent n be Pn Π= , Pn Π= 2 and Pn Π= 4 . Every factor of exponent n has the Fermat’s equation [1-7]. In complex trigonometric functions let exponent n be Pn Π= , Pn Π= 2 and Pn Π= 4 . Every factor of exponent n has Fermat’s equation [1-7]. Using modular elliptic curves Wiles and Taylor prove FLT [9, 10]. This is not the proof that Fermat thought to have had. The classical theory of automorphic functions, created by Klein and Poincare, was concerned with the study of analytic functions in the unit circle that are invariant under a discrete group of

    transformation. Automorphic functions are the generalization of trigonometric, hyperbolic, elliptic, and certain other functions of elementary analysis. The complex trigonometric functions and complex hyperbolic functions have a wide application in mathematics and physics. Acknowledgments.

    AbstractAs it is well known, the Riemann hypothesis on the zeros of the ζ(s)function has been assumed to be true in various basic developments ofthe 20-th century mathematics, although it has never been proved tobe correct. The need for a resolution of this open historical problemhas been voiced by several distinguished mathematicians. By using pre-ceding works, in this paper we present comprehensive disproofs of theRiemann hypothesis. Moreover, in 1994 the author discovered the arith-metic function Jn(ω) that can replace Riemann’s ζ(s) function in view ofits proved features: if Jn(ω) 6= 0, then the function has infinitely manyprime solutions; and if Jn(ω) = 0, then the function has finitely manyprime solutions. By using the Jiang J2(ω) function we prove the twinprime theorem, Goldbach’s theorem and the prime theorem of the formx2 + 1. Due to the importance of resolving the historical open natureof the Riemann hypothesis, comments by interested colleagues are heresolicited.

  • 1. Introduction

    In 1859 Riemann defined the zeta function[1]

    ζ(s) =∏p

    (1− p−s)−1 =∞∑

    n=1

    1

    ns, (1)

    where s = σ + ti, i =√−1, σ and t are real, p ranges over all primes.

    ζ(s) satisfies the functional equation [2]

    π−s2 Γ(

    s

    2)ζ(s) = π−

    (1−s)2 Γ(

    1− s2

    )ζ(1− s). (2)

    From (2) we haveζ(ti) 6= 0. (3)

    Riemann conjectured that ζ(s) has infinitely many zeros in 0 ≤ σ ≤ 1,called the critical strip. Riemann further made the remarkable conjecturethat the zeros of ζ(s) in the critical strip all lie on the central line σ = 1/2,a conjecture called the famous Riemann hypothesis (RH).

    It was stated by Hardy in 1914 that infinitely many zeros lie on theline; A. Selberg stated in 1942 that a positive proportion at least of allthe zeros lie on the line; Levinson stated in 1974 that more than onethird of the zeros lie on the line; Conrey stated in 1989 that at least twofifths of the zeros lie on the line.

    The use of the RH then lead to many mathematical problems, suchas the generalized Riemann conjecture, Artin’s conjecture, Weil’s con-jecture, Langlands’ program, quantum chaos, the hypothetical Riemannflow [3, 4], the zeta functions and L-functions of an algebraic variety andother studies. Similarly, it is possible to prove many theorems by usingthe RH.

    However, the RH remains a basically unproved conjecture to thisday. In fact, Hilbert properly stated in 199 that the problem of provingor disproving the RH is one of the most important problems confronting20th century mathematicians. In 2000 Griffiths and Graham pointed outthat the RH is the first challenging problem for the 21st century. Theproof of the RH then become the millennium prize problem.

    In 1997 we studied the tables of the Riemann zeta function [5] andreached preliminary results indicating that the RH is false [6, 7, 8]. In

    2

  • this paper we present a comprehensive disproof of the RH and show thatthe computation of all zeros of the ζ(1/2 + ti) function done during thepast 100 years is in error, as preliminarily indicated in Refs. [9, 10, 11].Since the RH is false, all theorems and conjectures based to the same arealso false.

    2. Disproofs of Riemann’s Hypothesis

    Theorem 1. ζ(s) has no zeros in the critical strip, that is ζ(s) 6= 0,where 0 ≤ σ ≤ 1.

    Proof 1. From (1) we have

    1

    ζ(s)=

    ∏p

    (1− 1ps

    ) = Reθi, (4)

    where

    R =∏p

    Rp, Rp =

    √1− 2 cos(t log p)

    pσ+

    1

    p2σ, (5)

    θ =∑p

    θp, θp = tan−1 sin(t log p)

    pσ − cos(t log p) . (6)

    If σ = 0, from (5) we have Rp =√

    2√

    1− cos(t log p). If cos(t log p) =1, we have Rp = 0 then R = 0. If σ > 0 from (5) we have Rp 6= 0.ζ(s) = 0 if and only if Re ζ(s) = 0 and Im ζ(s) = 0, that is R = ∞. From(5) we have that if cos(t log p) ≤ 0 then Rp > 1 and if cos(t log p) > 0then Rp < 1. cos(t log p) is independent of the real part σ, but maywell depend on primes p and imaginary part t. We write m+(t) for thenumber of primes p satisfying cos(t log p) > 0, m−(t) for the number ofprimes p satisfying cos(t log p) ≤ 0.

    For cos(t log p) > 0, we have

    1 > Rp(1 + ti) > Rp(0.5 + ti). (7)

    If m+(t1) is much greater than m−(t1) such that R(0.5 + t1i) = min.From (5), (6) and (7) we have for given t1

    minR(σ1 + t1i) > minR(1 + t1i) > minR(0.5 + t1i)

    > minR(σ2 + t1i) → 0,

    3

  • (8)

    θ(σ1 + t1i) = θ(1 + t1i) = θ(0.5 + t1i) = θ(σ2 + t1i) = const (9)

    where σ1 > 1 and 0 ≤ σ2 < 0.5.Since | ζ(s) |= 1

    Rfrom (8) we have

    max | ζ(σ1 + t1i) |< max | ζ(1 + t1i) |

    < max | ζ(0.5 + t1i) |< max | ζ(σ2 + t1i) |→ ∞. (10)For cos(t log p) < 0 we have

    1 < Rp(0.5 + ti) < Rp(0.4 + ti) < Rp(0.3 + ti). (11)

    If m−(t1) is much greater than m+(t1) such that R(0.5 + t1i) = max.From (5), (6) and (11) we have for given t1

    maxR(σ1 + t1i) < maxR(0.5 + t1i) < maxR(0.4 + t1i),

    < maxR(0.3 + t1i) < maxR(σ2 + t1i) 6= ∞, (12)

    θ(σ1 + t1i) = θ(0.5 + t1i) = θ(0.4 + t1i)

    = θ(0.3 + t1i) = θ(σ2 + t1i) = const,

    (13)

    where σ1 > 0.5 and 0 ≤ σ2 < 0.3.Since | ζ(s) |= 1

    Rfrom (12) we have

    min | ζ(σ1 + t1i) |> min | ζ(0.5 + t1i) |> min | ζ(0.4 + t1i) |>

    min | ζ(0.3 + t1i) |> min | ζ(σ2 + t1i) |6= 0. (14)Proof 2. We define the beta function

    where λ(1) = 1, λ(n) = (−1)a1+···+ak if n = pa11 · · · pakk , t 6= 0.

    β(s)=

    where

    θ̄ =∑p

    θ̄p, θ̄p = tan−1 − sin(t log p)

    pσ + cos(t log p). (18)

    For cos(t log p) < 0, we have

    1 > R̄p(1 + ti) > R̄p(0.5 + ti). (19)

    If m−(t1) is much greater than m+(t1) such that R̄(0.5 + t1i) = min.From (17), (18) and (19) we have for given t1

    minR̄(σ1 + t1i) > minR̄(1 + t1i) > minR̄(0.5 + t1i)

    > minR̄(σ2 + t1i) → 0, (20)θ̄(σ1 + t1i) = θ̄(1 + t1i) = θ̄(0.5 + t1i) = θ̄(σ2 + t1i) = const, (21)

    where σ1 > and 0 ≤ σ2 < 0.5.Since | β(s) |= 1

    R̄from (20) we have

    max | β(σ1 + t1i) |< max | β(1 + t1i) |

    < max | β(0.5 + t1i) |< max | β(σ2 + t1i) |→ ∞. (22)For cos(t log p) > 0 we have

    1 < R̄p(0.5 + ti) < R̄p(0.4 + ti) < R̄p(0.3 + ti). (23)

    If m+(t1) is much greater than m−(t1) such that that R̄(0.5+t1i) = max.From (17), (18) and (23) we have for given t1

    maxR̄(σ1 + t1i) < maxR̄(0.5 + t1i) < maxR̄(0.4 + t1i)

    < maxR̄(0.3 + t1i) < maxR̄(σ2 + t1i) 6= ∞, (24)

    = θ̄(0.3 + t1i) = θ̄(σ2 + t1i) = const,

    (25)

    where σ1 > 0.5 and 0 ≤ σ2 < 0.3.Since | β(s) |= 1

    R̄from (24) we have

    min | β(σ1 + t1i) |> min | β(0.5 + t1i) |

    > min | β(0.4 + t1i) |>

    min | β(0.3 + t1i) |> min | β(σ2 + t1i) |6= 0. (26)From (1) and (15) we have

    ζ(2s) = ζ(s)β(s). (27)

    In 1896 J. Hadamard and de la Vallee Poussin proved independently| ζ(1 + ti) |6= 0. From (27) we have

    | ζ(1 + 2ti) |=| ζ(12

    + ti) || β(12

    + ti) |6= 0. (28)

    From (28) we have

    | ζ(12

    + ti) |6= 0 and | β(12

    + ti) |6= 0. (29)

    ζ(s) and β(s) are the dual functions. From (22) we have

    | β(12

    + ti) |6= ∞. (30)

    Therefore we have

    | ζ(12

    + ti) |6= 0. (31)In the same way we have

    | ζ(12

    + 2ti) |=| ζ(14

    + ti) || β(14

    + ti) |6= 0. (32)

  • From (32) we have

    | ζ(14

    + ti) |6= 0 and | β(14

    + ti) |6= 0. (33)

    In the same way we have

    | ζ( 12n

    As n →∞ we have| ζ(ti) |6= 0. (35)

    m=1

    If ζ(s) had a zero at 12+ ti, then log | ζ(σ + ti) | would tend to −∞ as σ

    tends to 12

    from the right. From (36) we have

    2+ eti) |6= 0 for sufficiently large even number H.

    Min | ζ(12+ ti) ≈ 0 but 6= 0. The computation of all zeros of ζ(1

    is error, which satisfies the the error RH.From (39) we have

    cos 2θ + 4 cos θ + 3 = 2(1 + cos θ)2,

    cos 4θ + 8 cos 3θ + 28 cos 2θ + 56 cos θ + 35 = 8(1 + cos θ)4,

    +495 cos 2θ + 792 cos θ + 462 = 32(1 + cos θ)6.

    3. The Arithmetic Function Jn(ω) Replacing Rie-mann’s Hypothesis

    In view of the preceding results, the RH has no value for the study ofprime distributions. In 1994 the author discover the arithmetic functionJn(ω) [12, 13] that is able to take the place of Riemann’s zeta-functionsand L-functions because of the following properties: Jn(ω) 6= 0, then thefunction has infinitely many prime solutions; and if Jn(ω) = 0, then thefunction has finitely many prime solutions.

    By using Jiang’s Jn(ω) function we have proved numerous theoremsincluding the twin prime theorem, Goldbach’s theorem, the prime k-tuples theorem, Santilli’s theory for a prime table, the theorem of finiteFermat primes, the theorem of finite Mersenne primes, the theorem offinite repunit primes, there are infinitely many triples of n, n+1 and n+2that each is the product of k distinct primes, there are infinitely manyCarmichael numbers which are product of exactly five primes, there thereare finitely many Carmichael numbers which are product of exactly sixprimes · · · in the prime distributions [14]. We give some theorems below

    Theorem 2. Twin prime theorem: p1 = p + 2.

    p)) 6= 0.

    Since J2(ω) 6= 0, there are infinitely many primes p such that p1 and p2are primes.

    Theorem 8. The prime 13-tuples theorem: p+b: b = 0, 4, 6, 10, 16, 18,24, 28, 34, 40, 46, 48, 90.Since J2(13) = 0, there are no prime 13-tuples if p 6= 13.

    Theorem 9. The prime 14-tuples theorem: p+b: b = 0, 2, 6, 8, 12, 18,20, 26, 30, 32, 36, 42, 48, 50.We have

    J2(ω) = 300∏

    29≤p≤pi(p− 14) 6= 0.

    Since J2(ω) 6= 0, there are infinitely many prime 14-tuples.Theorem 10. p1 = 6m + 1, p2 = 12m + 1, p3 = 18m + 1, p4 =

    36m + 1, p5 = 72m + 1.We have

    J2(ω) = 12∏

    13≤p≤pi(p− 6) 6= 0.

    Since J2(ω) 6= 0, there are infinitely many integers m such that p1, p2, p3, p4and p5 are primes. n = p1p2p3p4p5 is the Carmichael numbers.

    Theorem 11. p3 = p1 + p2 + p1p2.We have

    J3(ω) =∏

    3≤p≤pi(p2 − 3p + 3) 6= 0.

    Since J3(ω) 6= 0, there are infinitely many primes p1 and p2 such that p3is a prime.

    Theorem 12. p3 = (p1 + 1)5 + p2.

    We haveJ3(ω) =

    3≤p≤pi(p2 − 3p + 3) 6= 0.

  • Since J3(ω) 6= 0, there are infinitely many primes p1 and p2 such that p3is a prime.

    Theorem 14. Each of n, n + 1 and n + 2 is the product of k distinctprimes.

    Suppose that each of m1,m2 = m1+1 and m3 = m1+2 is the productof k − 1 distinct primes. We define

    p1 = 2m2m3x + 1, p2 = 2m1m3x + 1, p3 = 2m1m2x + 1. (41)

    We have the arithmetic function

    J2(ω) =∏

    3≤p≤pi(p− 4− χ(p)) 6= 0, (42)

    where χ(p) = −2 if p | m1m2m3; χ(p) = 0 otherwise.Since J2(ω) 6= 0, there exist infinitely many integers x such that p1, p2and p3 are primes.

    ¿From (41) we have n = m1p1 = 2m1m2m3x+m1, n+1 = m1p1 +1 =2m1m2m3x + m1 + 1 = m2(2m1m3x + 1) = m2p2, n + 2 = m1p1 + 2 =2m1m2m3x + m1 + 2 = m3(2m1m2x + 1) = m3p3. If p1, p2 and p3 areprimes, then each of n, n + 1 and n + 2 is the product of k distinctprimes. For example, n = 1727913 = 3× 11× 52361, n + 1 = 1727914 =2× 17× 50821, n + 2 = 1727915 = 5× 7× 49369.

    Jn(ω) is a generalization of Euler’s proof for the existence of infinitelymany primes. It has a wide application in various fields.

    Fermat Last Theorem And

    Automorphic Functions And

    Fermat’s Last Theorem(3) (Fermat’s Proof of FLT)

    Chun-Xuan Jiang P. O. Box 3924, Beijing 100854, P. R. China

    [email protected]

    Abstract In 1637 Fermat wrote: “It is impossible to separate a cube into two cubes, or a biquadrate into

    two biquadrates, or in general any power higher than the second into powers of like degree: I have discovered a truly marvelous proof, which this margin is too small to contain.”

    This means: ( 2)n n nx y z n+ = > has no integer solutions, all different from 0(i.e., it has only the trivial solution, where one of the integers is equal to 0). It has been called Fermat’s last

    theorem (FLT). It suffices to prove FLT for exponent 4 and every prime exponent P . Fermat proved FLT for exponent 4. Euler proved FLT for exponent 3.

    In this paper using automorphic functions we prove FLT for exponents 4P and P , where P is an odd prime. We rediscover the Fermat proof. The proof of FLT must be direct. But indirect proof of FLT is disbelieving.

    In 1974 Jiang found out Euler formula of the cyclotomic real numbers in the cyclotomic fields

    Fermat proved that (14) has no rational solutions for exponent 4 [8]. Therefor we prove that (17) has no rational solutions for prime exponent P . Remark. Mathematicians said Fermat could not possibly had a proof, because they do not understand FLT.In complex hyperbolic functions let exponent n be n P= Π , 2n P= Π and

    4n P= Π . Every factor of exponent n has Fermat’s equation [1-7]. Using modular elliptic curves Wiles and Taylor prove FLT [9,10]. This is not the proof that Fermat thought to have had. The

    classical theory of automorphic functions,created by Klein and Poincare, was concerned with the study of analytic functions in the unit circle that are invariant under a discrete group of transformation. Automorphic functions are the generalization of trigonometric, hyperbolic elliptic, and certain other functions of elementary analysis. The complex trigonometric functions and complex hyperbolic functions have a wide application in mathematics and physics. Acknowledgments.

    1637 Fermat wrote: “It is impossible to separate a cube into two cubes, or a biquadrate into two biquadrates, or in general any power higher than the second into powers of like degree: I have discovered a truly marvelous proof, which this margin is too small to contain.”

    This means: ( 2)n n nx y z n+ = > has no integer solutions, all different from 0(i.e., it has only the trivial solution, where one of the integers is equal to 0). It has been called Fermat’s last

    theorem (FLT). It suffices to prove FLT for exponent 4. and every prime exponent P . Fermat proved FLT for exponent 4. Euler proved FLT for exponent 3.

    In this paper using automorphic functions we prove FLT for exponents 3P and P , where P is an odd prime. We find the Fermat proof. The proof of FLT must be direct. But indirect proof of FLT is disbelieving..

    Fermat proved that (29) has no integer solutions for exponent 4 [8]. Therefore we prove that (30) has no integer solutions for all prime exponent P [2,5,7].This is the proof that Fermat thought to have had. Remark. It suffices to prove FLT for exponent 4.

    Abstract In 1637 Fermat wrote: “It is impossible to separate a cube into two cubes, or a biquadrate into two biquadrates, or in general any power higher than the second into powers of like degree: I have discovered a truly marvelous proof, which this margin is too small to contain.”

    This means: ( 2)n n nx y z n+ = > has no integer solutions, all different from 0(i.e., it has only the trivial solution, where one of the integers is equal to 0). It has been called

    Fermat’s last theorem (FLT). It suffices to prove FLT for exponent 4 and every prime

    exponent P . Fermat proved FLT for exponent 4. Euler proved FLT for exponent 3[8]. In this paper using automorphic functions we prove FLT for exponents 6P and 2P , where P is an odd prime. The proof of FLT must be direct. But indirect proof of FLT is disbelieving. In 1974 Jiang found out Euler formula of the cyclotomic real numbers in the cyclotomic fields

    Euler prove that (13) has no rational solutions for exponent 3 [8]. Therefore we prove that (16) has no rational solutions for exponent 4P [5,7]. Remark. It suffices to prove FLT for exponent 4. Let 4n P= , where P is an odd prime. We have the Fermat’s equation for exponent 4P and the Fermat’s equation for exponent P [5,7]. This is the proof that Fermat thought to have had. In complex hyperbolic functions let exponent n be n P= Π , 2n P= Π and 4n P= Π . Every factor of exponent n has Fermat’s equation [1-7]. In complex trigonometric functions let exponent n be n P= Π , 2n P= Π and 4n P= Π . Every factor of exponent n has Fermat’s equation [1-7]. Using modular elliptic curves Wiles and Taylor prove FLT [9,10]. This is not the proof that Fermat thought to have had. The classical theory of automorphic functions, created by Klein and Poincarè, was concerned with the study of analytic functions in the unit circle that are invariant under a discrete group of transformation. Automorphic funciton are the generalization of trigonometric, hyperbolic, elliptic, and certain other functions of elementary analysis. The automorphic functions (complex trigonometric functions and complex hyperbolic functions) have a wide application in mathematics and physics.
