On solutions of $f (x) + f (a_{1} x) + ... + f (a_{N} x) = 0$ and related equations

J. M. Almira, Kh. F. Abu-Helaiel

We study some properties of the solutions of the functional equation $f (x) + f (a_{1} x) + ... + f (a_{N} x) = 0,$ which was introduced in the literature by Mora, Cherruault and Ziadi in 1999, f…

A note on classical and p-adic Fréchet functional equations with restrictions

J. M. Almira

Given X,Y two Q-vector spaces, and f:X -> Y, we study under which conditions on the sets $B_{k} \subseteq X$ , k=1,...,s, if $Δ_{h_{1} h_{2} ... h_{s}} f (x) = 0$ for all x in X and h_k in B_k, k=…
