Global Convergence of the Gursky-Malchiodi -curvature Flow

Liuwei Gong, Sanghoon Lee, Juncheng Wei

In their seminal work, Gursky and Malchiodi introduced a non-local conformal flow in dimensions to resolve the constant -curvature problem. They proved sequential con…

The Rabinowitz continuum of subcritical Gelfand problems and free boundary-type equations arising in plasma physics

Daniele Bartolucci, Aleks Jevnikar, Juncheng Wei +1

The qualitative behavior of the Rabinowitz unbounded continuum of subcritical Gelfand problems is well known on balls in any dimension. We don't know of any such sharp and detailed…

A Lane-Emden system of free boundary type: existence, uniqueness and monotonicity of solutions

Daniele Bartolucci, Yeyao Hu, Aleks Jevnikar +2

We consider a Hamiltonian system of free boundary type, showing first uniform bounds and existence of solutions and of the free boundary. Then, for any smooth and bounded domain, w…

Classification of singular limits for free boundary and singularly perturbed elliptic problems: the Dancer-Yan spikes revisited

Daniele Bartolucci, Aleks Jevnikar, Juncheng Wei +1

We classify the singular limits relative to a free boundary problem arising in plasma physics in dimension , under suitable natural integral bounds. It turns out that one of t…

Symmetry in Serrin-type overdetermined problems

Daomin Cao, Juncheng Wei, Weicheng Zhan

This paper investigates the geometric constraints imposed on a domain by overdetermined problems for partial differential equations. Serrin's symmetry results are extended to overd…

Localized patterns in the Gierer Meinhardt model on a cycle graph

Theodore Kolokolnikov, Juncheng Wei, Shuangquan Xie

In this study, we provide a detailed analysis of the spike solutions and their stability for theGierer-Meinhardt model on discrete lattices. We explore several phenomena that have…

An Ohta-Kawasaki Model set on the space

Lorena Aguirre Salazar, Xin Yang Lu, Jun-cheng Wei

We examine a non-local diffuse interface energy with Coulomb repulsion in three dimensions inspired by the Thomas-Fermi-Dirac-von Weizsäcker, and the Ohta-Kawasaki models. We consi…
