Keywords:
measurable solutions; system; Shannon’s entropy
Summary:
In this paper, measurable solutions of a functional equation with four unknown functions are obtained. As an application of the measurable solutions a joint characterization of Shannon's entropy and entropy of type $\beta$ is given.
