Summary: In this paper, we study the existence of multiple nonnegative solutions for second-order boundary-value problems of differential equations with sign-changing nonlinearities. Our main tools are the fixed-point theorem in double cones and the Leggett-Williams fixed point theorem. We present also the integral kernel associated with the boundary-value problem.
Classification : 34B10, 34B18
Keywords: nonnegative solutions, fixed-point theorem in double cones, integral kernel, integral boundary conditions
