On multiple sign-changing solutions for some second-order integral boundary value problems. (English) Zbl 1211.34020

Summary: By employing fixed point index theory and Leray-Schauder degree theory, we obtain the existence and multiplicity of sign-changing solutions for nonlinear second-order differential equations with integral boundary value conditions.
