On involutions satisfying a system of functional equations



Abstract

In this paper we investigate a system of functional equations
NN = id
Nfk = fp-1-k∘N   k=0,...,p-1
in finite and infinite interval, where f0,...,fp-1 are given real functions. Under suitable assumptions on fi, we prove that the system has a unique solution and this solution is continuous and decreasing.
