非局部椭圆型方程共振问题的可解性

On the solvability of resonance problems for nonlocal elliptic equations

Sarika Goyal

摘要:

本文考虑如下问题:$$ \quad \left\{ \begin{array}{lr} \quad (-Δ)^s u = αu^+ -βu^{-} + f(u) + h \; \text{in}\;Ω\quad \quad \quad \quad u =0 \; \text{on}\; \mathbb{R}^n\setminus Ω, \end{array} \right. $$其中$Ω\subset \mathbb{R}^n$是具有Lipschitz边界的有界域,$n> 2s$,$0<s<1$,$(α, β) \in \mathbb{R}^2$,$f: \mathbb{R}\to \mathbb{R}$是有界连续函数,$h\in L^2(Ω)$ .我们证明存在的结果在两种情况下:第一,非共振的情况下,其中$(α,β)$是不是一个元素的Fučik谱。第二,共振情况,其中$(α,β)$是Fučik谱的元素。我们的存在性结果作为鞍点定理的一个应用。它将Laplace算子的一些结果推广到非局部算子。

英文摘要:

In this article, we consider the following problem: $$ \quad \left\{ \begin{array}{lr} \quad (-Δ)^s u = αu^+ -βu^{-} + f(u) + h \; \text{in}\;Ω\quad \quad \quad \quad u =0 \; \text{on}\; \mathbb{R}^n\setminus Ω, \end{array} \right. $$ where $Ω\subset \mathbb{R}^n$ is a bounded domain with Lipschitz boundary, $n> 2s$, $0<s<1$, $(α, β) \in \mathbb{R}^2$, $f: \mathbb{R}\to \mathbb{R}$ is a bounded and continuous function and $h\in L^2(Ω)$. We prove the existence results in two cases: First, the nonresonance case, where $(α,β)$ is not an element of the Fučik spectrum. Second, the resonance case, where $(α,β)$ is an element of the Fučik spectrum. Our existence results follows as an application of the Saddle point Theorem. It extends some results, well known for Laplace operator, to the nonlocal operator.
