In this paper we study general solutions of the following Pexider functional equation

\\\\\\\\begin{eqnarray}

(4-k)f_{1}(\\\\\\\\sum_{i=1}^{k}x_{i})+

\\\\\\\\sum_{j=2}^{k}f_{j}((\\\\\\\\sum_{i=1,i\ ...

In this paper we study general solutions and generalized Hyers-Ulam-Rassias stability of the following n-dimentional function equation

\\\\[

f(\\\\sum_{i=1}^{k}x_{i})+(k-2)\\\\sum_{i=1}^{k}f(x_{i})=\\\\sum ...
