Abstract
The aim of this paper is to investigate the superstability problem for the pexiderized trigonometric functional equation ∑ϕ∈Φ∫Kf(xkϕ(y)k-1)duK(k) = |Φ|g(x)h(y), x,y ∈ G,where G is any topological group, K is a compact subgroup of G, ωK is the normalized Haar measure of K, Φ is a finite group of K-invariant morphisms of G and f,g,h are continuous complex-valued functions.Consequently, we have generalized the results of stability for d'Alembert's and Wilson's equations by R.
