“The” versus “a/an”

Most nouns in English in their singular form require an article;we will discuss exceptions from this rule later.

In order to address an unspecified object, property,phenomenon, etc., the indefinite articles “a” or “an” are used(depending on the pronunciation of the word) for nouns insingular form, and no article at all for nouns in plural form.

In order to address a specified object, property, phenomenon,etc., the definite article “the” is used, for both the singular andthe plural form. The specification may have been given in earliersentences, may take place in the same sentence, or may beimplicit in the meaning of the noun.

The government imposed a curfew.

They conducted a series of experiments. Most of the time,the experiments in the series were inconclusive. However,the ultimate experiment supported a longstandinghypothesis.

We fix a compact topological space X. Next, we choose aclosed subset of the space X.

Even if an object is unique,

it can still be unspecified at themoment we first address it:

The Banach Fixed Point Theorem shows the existence of aunique fixed point of the function f . The fixed point wehave found is a root of the polynomial p. We leave it tothe reader to show that it is in fact the unique root withthe required properties.

The author made a mistake if he meant to say “A rationalnumber n has a multiplicative inverse”, as this is stating thatevery rational number n has a multiplicative inverse (but 0 doesnot).Hence the sentence should be “The rational number n has amultiplicative inverse” and should refer to a range of nonzerorational numbers n previously specified.
