Multiple Positive Solutions for Nonlinear Third-Order Boundary Value Problems in Banach Spaces
This paper deals with the positive solutions of nonlinear boundary value problems in Banach spaces. By using fixed point index theory, some sufficient conditions for the existence of at least one or two positive solutions to boundary value problems in Banach spaces are obtained. An example illustrating the main results …
