一类二阶多点共振边值问题解的存在性

The Existence of Solution to the Problem on Second Order Multi-Point Resonance Boundary Value

通过定义适当的投影算子,利用上下解方法,给出了dim ker L=2时二阶多点共振边值问题解的存在性的判定方法,进一步推广了文献[1-5]中的结果.

By the definition of fixed projection operator, the employment of upper and lower solution method, giving defining methods of the existence of solution to muhipoint resonance boundary value for dimker L=2, further more generalizing the results of literature [1-5].
