In the theory of optimization an essential role is played by the differentiability of convex functions. In this paper we shall try to extend the results concerning differentiability to a larger class of functions called strongly alpha(.)-paraconvex. Let (X, (|.||) be a real Banach space. Let f(x) be a real valued strongly alpha(.)-paraconvex function denned on an open convex subset Omega [is a subset is] X, i.e. f(tx+(1-t)y)
