具有凹凸非线性项的非局部方程的多重性结果和变号解

Multiplicity results and sign changing solutions of non-local equations with concave-convex nonlinearities

Mousomi Bhakta, Debangana Mukherjee

摘要:

本文证明了由具有凹凸非线性项和齐次Dirichlet边界条件的非局部积分微分算子$L_K$驱动的下列方程的无穷多个非平凡解的存在性,其中\begin{eqnarray*} \mathcal{L}_{K} u + μ\, |u|^{q-1}u + λ\,|u|^{p-1}u &=& 0 \quad\text{in}\quad Ω, \\[2mm] u&=&0 \quad\mbox{in}\quad\mathbb{R}^N\setminusΩ, \end{eqnarray*}是$\mathbb{R}^N$,$N>2s$,$s\in(0, 1)$,$0<q<1<p\leq \frac{N+2s}{N-2s}$中的光滑有界区域.此外,当$L_K$约简为分数拉普拉斯算子$-(-Δ)^s $,$p=\frac{N+2s}{N-2s}$,$\frac{1}{2}(\frac{N+2s}{N-2s})<q<1$,$N>6s$,$λ=1$时,我们发现$μ^*>0$使得对于任何$μ\in(0,μ^*)$,至少存在一个变号解.

英文摘要:

In this paper we prove the existence of infinitely many nontrivial solutions of the following equations driven by a nonlocal integro-differential operator $L_K$ with concave-convex nonlinearities and homogeneous Dirichlet boundary conditions \begin{eqnarray*} \mathcal{L}_{K} u + μ\, |u|^{q-1}u + λ\,|u|^{p-1}u &=& 0 \quad\text{in}\quad Ω, \\[2mm] u&=&0 \quad\mbox{in}\quad\mathbb{R}^N\setminusΩ, \end{eqnarray*} where $Ω$ is a smooth bounded domain in $\mathbb{R}^N$, $N>2s$, $s\in(0, 1)$, $0<q<1<p\leq \frac{N+2s}{N-2s}$. Moreover, when $L_K$ reduces to the fractional laplacian operator $-(-Δ)^s $, $p=\frac{N+2s}{N-2s}$, $\frac{1}{2}(\frac{N+2s}{N-2s})<q<1$, $N>6s$, $λ=1$, we find $μ^*>0$ such that for any $μ\in(0,μ^*)$, there exists at least one sign changing solution.
