EXISTENCE AND MULTIPLICITY OF POSITIVE SOLUTIONS FOR THIRD-ORDER MULTI-POINT BOUNDARY VALUE PROBLEM WITH SIGN CHANGING NONLINEARITY
摘要
Abstract
In this paper,existence of positive solution of a kind of boundary value problem of third order differential equation with changing sign nonlinearity is considered.By using the fixed point theorem and nonlinear functional analysis method,the existence of positive solution is established,which generalizes the existing literature.关键词
