我们考虑问题,其中Ω是RN中的外部区域,N≥3,α∈(0,N),p∈[2,2N−αN−2),W∈C0(RN),[公式:见正文],并且W(x)→V∞>0为|X| →∞。在关于Ω和W的对称性假设下,我们证明了该问题存在一个正解和多个变号解,且能量很小.
We consider the problem where Ω is an exterior domain in RN, N≥3,α∈(0,N), p∈[2,2N−αN−2),W∈C0(RN), [Formula: see text] , and W(x)→V∞>0 as |x|→∞. Under symmetry assumptions on Ω and W, which allow finite symmetries, and some assumptions on the decay of W at infinity, we establish the existence of a positive solution and multiple sign changing solutions to this problem, having small energy.
