Multiplicity of Positive Periodic Solutions of Singular Semipositone Third-Order Boundary Value Problems
We establish the existence of multiple positive solutions for a singular nonlinear third-order periodic boundary value problem. We are mainly interested in the semipositone case. The proof relies on a nonlinear alternative principle of Leray-Schauder, together with a truncation technique.
