A Kannappan-cosine functional equation on semigroups

Ahmed Jafar, Omar Ajebbar, Elhoucien Elqorachi

We determine the complex-valued solutions of the Kannappan cosine functional law $g (x y z_{0}) = g (x) g (y) - f (x) f (y)$ , $x, y \in S$ , where $S$ is a semigroup and $z_{0}$ is a fixed element…
