On alpha(.)-monotone multifunctions and differentiability of strongly alpha(.)-paraconvex functions

Let (X, d) be a metric space. Let [Phi] be a family of real-valued functions defined on X. The paper provides the suf ficient conditions, warranting that on alpha(.)-monotone multifunction [Gamma : X --> 2^Phi] is single-valued and continuous on a weakly angle-small set. As an application it is shown that a strongly alpha(.)-paraconvex (i.e. uniformly approximate convex) function defined on an open convex subset of a Banach space having separable dual is Frechet differentiable on a residual set.
