We establish critical groups estimates for the weak solutions of in Ω and on ∂Ω via Morse index, where Ω is a bounded domain, and for all , and for all , . The proof relies on new uniform Sobolev inequalities for approximating problems. We also prove critical groups estimates when Ω is the ball or the annulus and f is a sign changing function.

我们为弱解建立关键组估计单位为 Ω 和通过莫尔斯指数计算 ∂Ω,其中 Ω 是有界域,和对全部,和对全部,。该证明依赖于新的统一索博列夫不等式来近似问题。我们还证明了当 Ω 是球或环且f是变号函数时的临界群估计。
