一类径向加权完全非线性方程的动力系统方法

A dynamical system approach to a class of radial weighted fully nonlinear equations

Liliane Maia, Gabrielle Nornberg, Filomena Pacella

摘要:

本文研究了一类含Pucci极值算子的加权完全非线性方程径向正解的存在性、不存在性及分类。我们的结果完全是基于一个自治的二次系统,这是经过适当的变换后得到的动力学分析。该方法允许以统一的方式处理正则解和奇异解,而不使用能量参数。特别地,我们恢复了已知的结果正则解的完全非线性非加权问题的替代证明。我们还稍微改进了极值算子$\mathcal{M}^-$解的分类。

英文摘要:

In this paper we study existence, nonexistence and classification of radial positive solutions of some weighted fully nonlinear equations involving Pucci extremal operators. Our results are entirely based on the analysis of the dynamics induced by an autonomous quadratic system which is obtained after a suitable transformation. This method allows to treat both regular and singular solutions in a unified way, without using energy arguments. In particular we recover known results on regular solutions for the fully nonlinear non weighted problem by alternative proofs. We also slightly improve the classification of the solutions for the extremal operator $\mathcal{M}^-$.
