摘要

利用山路引理讨论了带共振的二阶差分方程边值问题解的多重性.把方程的解等价于泛函的临界点

且在一定的假设条件下采用函数的截断技术

结合非线性泛函分析中的变分方法

特别是临界群与Morse理论

分4步最终证明了方程至少存在两个解.

Abstract

Multiplicity of solutions of boundary value problems of second order discrete function with resonance was discussed by means of mountain pass lemma.The solution of the function is equivalent to the critical point of the functional.For the problems under certain conditions

four steps were taken in proving the existence of at least tow solutions by using the truncation technique

and variational method of nonlinear functional analysis

critical groups and the Morse theory.
