  • Abstract
    In this paper. (1) We determine the complex-valued solutions of the following variant of Van Vleck's functional equation where S is a topological semigroup, σ is a continuous involutive automorphism of S, and υ is a complex measure with compact support and which is σ-invariant. (3) We prove the superstability theorems of the rst functional equation.
