Abstract

We prove new results on Ulam stability of the nonhomogeneous Cauchy functional equation f ( x + y ) = f ( x ) + f ( y ) + d ( x , y ) in the class of mappings f from a square symmetric groupoid ( H , + ) into the set of reals R . The mapping d : H 2 → R is assumed to be given and satisfy some weak natural assumption. The equation arises naturally, e.g., in the theory of information in a description of generating functions of branching measures of information. Moreover, we provide a suitable example of application of our results in this area at the very end of this paper. The main tool used in the proofs is the Banach limit.
