CHARIFI, A.; ALMAHALEBI, M.  and  KABBAJ, S.. A generalization of Drygas functional equation. Proyecciones (Antofagasta) [online]. 2016, vol.35, n.2, pp.159-176. ISSN 0716-0917.

We obtain the Solutions of the following Drygas functional equation ∑ λ Φ f (x + λy + aλ ) = κf(x)+ ∑ λ Φ f(λy), x, y ∈ S where S is an abelian semigroup, G is an abelian group, f ∈ GS, Φ is a finite automorphism group of S with order k, and aλ ∈ S, λ∈Φ.

Keywords : Automorphism group; difference opera-tor; Drygas functional equation.
