Asymptotic behaviour and existence of positive solutions for mixed local nonlocal elliptic equations with Hardy potential

Shammi Malhotra, Sarika Goyal, K. Sreenadh

AI总结:

本文研究带Hardy位势的混合局部-非局部椭圆方程,通过变换建立解的一致渐近估计,分情形证明正解存在性,并在次线性小扰动下得到多解结果。

摘要:

我们研究由拉普拉斯算子与带Hardy位势的分数阶拉普拉斯算子叠加驱动的如下问题的正解存在性与多解性:其中Ω⊂ℝᴺ是具有光滑边界的有界区域,0<s<1,1<p<2*,2*=2N/(N−2),λ>0,μ∈(0,μ̄),其中μ̄=((N−2)/2)²。本文的研究目标有两方面。首先,我们通过一种合适的变换建立了该问题解的一致渐近估计。随后,我们根据指数p的取值分析了三种不同情形,并证明了正解的存在性。此外,在1<p<2的次线性情形下,我们证明了当分数阶拉普拉斯算子存在小扰动时,存在多个正解。

英文摘要:

We investigate the existence and multiplicity of positive solutions to the following problem driven by the superposition of the Laplacian and the fractional Laplacian with Hardy potential \begin{equation*} \left\{ \begin{aligned} -Δu + (-Δ)^s u - μ\frac{u}{|x|^2} &= λ|u|^{p-2} u + |u|^{2^*-2} u \quad \text{in } Ω\subset \mathbb{R}^N, u &= 0 \quad \text{in } \mathbb{R}^N \setminus Ω, \end{aligned} \right. \end{equation*} where $ Ω\subset \mathbb{R}^N $ is a bounded domain with smooth boundary, $ 0 < s < 1 $, $ 1 < p < 2^* $, with $ 2^* = \frac{2N}{N-2} $, $ λ> 0 $, and $ μ\in (0, \barμ) $ where $\bar μ= \left( \frac{N-2}{2} \right)^2$. The aim of this paper is twofold. First, we establish uniform asymptotic estimates for solutions of the problem by means of a suitable transformation. Then, according to the value of the exponent $p$, we analyze three distinct cases and prove the existence of a positive solution. Moreover, in the sublinear regime $1 < p < 2$, we demonstrate the existence of multiple positive solutions for small perturbations of the fractional Laplacian.
