在一类Ahmad-Lazer-Paul条件下,利用临界点理论中的广义山路引理得到了椭圆边值共振问题非平凡解的存在性.

边值问题;非平凡解;弱解

本文考虑如下椭圆边值问题非平凡解的存在性:

定理1的证明需要广义的山路引理可参见文献[3]中的定理5.3.

定理1的证明还需要文献[7]中的引理.

由引理1可知,我们只需证明下面的条件成立:

Existence of nontrivial solutions for a class of semilinear elliptic boundary value resonant problems is obtained under generalized Ahmad-Lazer-Paul type conditions by the generalized mountain pass lemma in the critical point theory.
