带有临界增长或超临界增长的分数阶Choquard方程解的存在性和多重性

该文考虑如下带有临界增长或超临界增长的分数阶Choquard方程(-Δ)su+u=f(u)+λ(|x|-μ * |u|q)|u|q-2u,x ∈ Ω,其中s ∈(0,1),μ ∈(0,N),N＞2s,q≥2*μ,s,f是一个连续函数.众所周知,在Hardy-Littlewood-Sobolev不等式意义下,2*ss=2...     

A NONTRIVIAL SOLUTION OF A QUASILINEAR ELLIPTIC EQUATION VIA DUAL APPROACH

In this article, we are concerned with the existence of solutions of a quasilinear elliptic equation in R~N which includes the so-called modified nonlinear Schrodinger equation as a special case. Combining the dual approach and the nonsmooth critical point theory, we obtain the existence of a nontrivial solution.
