On a functional equation related to two-variable Cauchy means
On a functional equation related to two-variable Cauchy means
In this paper, we are dealing with the solution of the functional equationconcerning the unknown functions ϕ, f and F defined on a same open subinterval of the reals.Improving the previous results related to this topic, we describe the solution triplets (ϕ, f, F ) assuming only the continuity of …
