Abstract:
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.
