A complete characterization of the existence of extremals for the Trudinger-Moser inequality on under sharp -perturbations

Lu Chen, Rou Jiang, Guozhen Lu +1

In this paper, we investigate the following critical Trudinger--Moser inequality on under sharp -perturbations: $$ S(λ,p) := \sup_{\substack{u\in H^{1}(\mathbb R…

Stability for Critical Points of the Hardy--Littlewood--Sobolev Inequality and a Dual Stability Framework

Lu Chen, Guozhen Lu, Hanli Tang

Although quantitative stability for critical points of the Sobolev and fractional Sobolev inequalities has been extensively studied, the corresponding stability theory for critical…

Quantization property of n-Laplacian mean field equation and sharp Moser-Onofri inequality

Lu Chen, Guozhen Lu, Bohan Wang

In this paper, we are concerned with the following -Laplacian mean field equation \[ \left\{ {\begin{array}{*{20}{c}} { - Δ_n u = λe^u} & {\rm in} \ \ Ω, \\ {\ \ \ \ u = 0} &…

Asymptotically sharp stability of Sobolev inequalities on the Heisenberg group with dimension-dependent constants

Lu Chen, Guozhen Lu, Hanli Tang +1

In this paper, we are concerned with the optimal asymptotic lower bound for the stability of Sobolev inequality on the Heisenberg group. We first establish the optimal local stabil…

Existence and Nonexistence of Extremals for Trudinger-Moser inequalities with type perturbation on any bounded planar domains

Lu Chen, Rou Jiang, Guozhen Lu +1

In this study, we investigate the perturbed Trudinger-Moser inequalities as follows:\[ S_Ω(λ,p)=\sup_{u\in H_{0}^{1}(Ω),\Vert\nabla u\Vert _{L^{2}\left( Ω\right) }\leq 1}\int_΅

Optimal stability of Hardy-Littlewood-Sobolev and Sobolev inequalities of arbitrary orders with dimension-dependent constants

Lu Chen, Guozhen Lu, Hanli Tang

Recently, Dolbeault-Esteban-Figalli-Frank-Loss [20] established the optimal stability of the first-order -Sobolev inequality with dimension-dependent constant. Subsequently, C…
