Implicity integral equations with discontinuous nonlinearities

In this paper, we establish the existence of at least one solution fora class of implicit integral equations with possibly discontinuos nonlinearities,which includes the well-known Chandrasekhar equation,among others. Our approach fully depends on a very recent resulton fixed points for increasing, not necessarilly continuous, operatorsin ordered Banach space due to G. Bonanno and S. A. Marano; see Theorem 1 below.
