We prove that the set of all weak solutions of the Volterra integral equation (1) is nonempty, compact and connected. Assume that D = (0;a) is a compact interval in R, E is a sequentially weakly complete Banach space, B =fx2 E :kxk6 bg. We prove the existence of a weak solution of the integral equation
