A stability result about a functional equation of Drygas on an Abelian group
Abstract
We prove a result on the stability of a generalized functional equation of Drygas with three additional terms f(-x + y + z), f(x-y + z) and f(x + y-z) for functions sending an abelian group to a Banach space, using a fixed point approach.
