In this equation parameter k is superficial and we can make it 1. Indeed, scaling x = kr (it is not an original Cartesian coordinate) we observe that equation becomes x2R ″ + xR ′ + (x2 − m2)R = 0. This is Bessel equation and its solutions (bounded at 0 --as our domain is a disk D = {r < a}) are ...
