ln this paper, a fixed-point theorem for condensing multivalued maps due to Martelli combined with the concept of upper and lower solutions is used to investigate the existence of solutions for first-order impulsive differential inclusions with nonlinear boundary conditions. (~) 2004 Elsevier Ltd. A
In this paper we consider a nonlinear parabolic problem with a discontinuous, nonmonotone nonlinearity. We assume the existence of an upper solution and a lower solution such that F . Using results from the theory of pseudomonotone operators and from the theory of multivalued analysis together with
