1. Green’s functions
Linear operator L; solve inhomogeneous eqn.
In n-d configuration space x :
where
Dirac’s delta distribution acts as unit w.r. to
convolution *:
In 4-d, account for retardation (speed c)
Retarded Green’s function:
Advanced Green’s function:
Using the light cone:
Retarded solution:
