具有奇异或零位势的径向nonlinear elliptic问题

Radial nonlinear elliptic problems with singular or vanishing potentials

Marino Badiale, Federica Zaccagni

摘要:

本文在径向势$A,V,K$的适当假设下,证明了非线性椭圆型方程\[ -\mathrm{div}(A(|x|)\nabla u)+V(|x|)u=K(|x|)f(u) \quad \text{in }\mathbb{R}^{N}, \] \noindent径向解的存在性.首先得到了径向加权索伯列夫空间到加权Lebesgue空间和的紧嵌入,然后利用标准变分技巧得到了存在性结果。

英文摘要:

In this paper we prove existence of radial solutions for the nonlinear elliptic problem \[ -\mathrm{div}(A(|x|)\nabla u)+V(|x|)u=K(|x|)f(u) \quad \text{in }\mathbb{R}^{N}, \] \noindent with suitable hypotheses on the radial potentials $A,V,K$. We first get compact embeddings of radial weighted Sobolev spaces into sum of weighted Lebesgue spaces, and then we apply standard variational techniques to get existence results.
