Nonexistence of extremals for an inequality of Adimurthi-Druet on a closed Riemann surface

Yunyan Yang

Based on a recent work of Mancini-Thizy [28], we obtain the nonexistence of extremals for an inequality of Adimurthi-Druet [1] on a closed Riemann surface $(Σ, g)$ . Precisely, if $λ…

Mean field equations on a closed Riemannian surface with the action of an isometric group

Yunyan Yang, Xiaobao Zhu

Let $(Σ, g)$ be a closed Riemannian surface, $G = {σ_{1}, \dots, σ_{N}}$ be an isometric group acting on it. Denote a positive integer $ℓ = in f_{x \in Σ} I (x)$ , where $I (x)$ is t…

A Trudinger-Moser inequality for conical metric in the unit ball

Yunyan Yang, Xiaobao Zhu

In this note, we prove a Trudinger-Moser inequality for conical metric in the unit ball. Precisely, let $B$ be the unit ball in $R^{N}$ $(N \geq 2)$ , $p > 1$ , $g=|x|^{…
