An extension of Van Vleck's functional equation for the sine

Bouikhalene Belaid, Elqorachi Elhoucien

In \cite{St3} H. Stetkær obtained the solutions of Van Vleck's functional equation for the sine $f (xτ (y) z_{0}) - f (x y z_{0}) = 2 f (x) f (y), x, y \in G,$ where $G$ is a semigroup, $τ$ is an…

Solutions and stability of a generalization of Wilson's equation

Bouikhalene Belaid, Elqorachi Elhoucien

In this paper we study the solutions and stability of the generalized Wilson's functional equation $\int_{G} f (x t y) d μ (t) + \int_{G} f (x t σ (y)) d μ (t) = 2 f (x) g (y), x, y \in G$ , where $G$ is…
