We consider the following noncoercive functional with the critical Sobolev exponent where , , , . We prove the existence of a nontrivial critical point via the mountain pass theorem and the multiplicity via Clark's theorem.

具有临界 Sobolev 指数的非强制泛函临界点的存在
我们考虑以下具有关键 Sobolev 指数的非强制泛函在哪里,,,. 我们通过山口定理证明了非平凡临界点的存在,并通过克拉克定理证明了多重性。
