Abstract: | In this article, the following concave and convex nonlinearities elliptic equations involving critical growth is considered,
where Ω ?
(N ≥ 3) is an open bounded domain with smooth boundary, 1 < q < 2,λ > 0.
is the critical Sobolev exponent,
is nonzero and nonnegative, and g ∈ C
is a positive function with k local maximum points. By the Nehari method and variational method, k + 1 positive solutions are obtained. Our results complement and optimize the previous work by Lin MR2870946, Nonlinear Anal. 75(2012) 2660-2671]. |
