Abstract

O'Regan fixed point theorem is used to establish an existence result for the fractional order integral equation x(t) = g(t)+ ?Ia f(.,x(.))(t), t?[0,1], a ? 0, where the vector-valued function is nonlinear weakly-weakly continuous. Moreover, existence of weak solutions to the Cauchy problem  dx/dt = f(t, x (t)), t ? [0,1], x(0) = x0, is obtained as a corollary.
