摘要：

We consider the following noncoercive functional with the critical Sobolev exponent I(u) = 1/2 integral(Omega)1/(1 + vertical bar u vertical bar)(2 alpha) vertical bar del u vertical bar(2)dx - lambda/q integral(Omega) vertical bar u vertical bar(q)dx - 1/2*(1 - alpha) integral(Omega) vertical bar u vertical bar(2)* (1- alpha) dx, where lambda > 0, 0 < alpha < (N + 2)/2N, 2 < q < 2* (1 - alpha), 2* = 2N/(N - 2). We prove the existence of a nontrivial critical point via the mountain pass theorem and the multiplicity via Clark's theorem.
