非线性Fredholm型积分方程多解的存在性

The Existence of Multiple Solutions for a Class of Nonlinear Fredholm type Integral Equations

本文在全空间上,利用拓扑度在适当的条件下证明了非线性Fredholm型积分方程存在多个解。

Under suitable conditions, we obtain the existence of multiple solutions for a class of nonlinear Fredholm type integral equations by using the topological degree in Banach space.
