On a new region for the Lane-Emden conjecture in higher dimensions
Kui Li, Mingxiang Li, Juncheng Wei
We study the Lane-Emden conjecture, which asserts the non-existence of non-trivial, non-negative solutions to the Lane-Emden system \[ -Îu = v^p, \quad -Îv = u^q, \quad x \in \ma…

A Remark On Case-Gursky-Vétois identity and its applications
Mingxiang Li, Juncheng Wei
Based on the works of Gursky (CMP, 1997), Vétois (Potential Anal., 2023) and Case (Crelle's journal, 2024), we make use of an Obata type formula established in these works to obta…
