Gradient estimates for -harmonic functions on Riemannian manifolds

Yuxin Dong, Hezi Lin, Weihao Zheng

In this paper, we study -harmonic functions on complete Riemannian manifolds using the Moser iteration method. A volume comparison theorem and a Sobolev embedding theorem ar…

Exponentially-growing Mode Instability on Reissner-Nordström--Anti-de-Sitter black holes

Weihao Zheng

We construct growing mode solutions to the uncharged and charged Klein-Gordon equations on the sub-extremal Reissner-Nordström--anti-de-Sitter (AdS) spacetime under reflecting (Di…
