In this paper we will investigate the superstability of the generalized d'Alembert type functional equations sum_{i=1}^{m}f(x+sigma^{i}(y))=kg(x)f(y) and sum_{i=1}^{m}f(x+sigma^{i}(y))=kf(x)g(y).
Abstract
In this paper we will investigate the superstability of the generalized d'Alembert type functional equations sum_{i=1}^{m}f(x+sigma^{i}(y))=kg(x)f(y) and sum_{i=1}^{m}f(x+sigma^{i}(y))=kf(x)g(y).
