Torsion energy with boundary mean zero condition
Qinfeng Li, Weihong Xie, Hang Yang
Motivated by establishing Neumann Talenti type comparison results, we concern the minimization of the following shape functional under volume constraint: \begin{align*} T(Ω):=\inf\…
A stronger constant rank theorem
Qinfeng Li, Lu Xu
Motivated from one-dimensional rigidity results of entire solutions to Liouville equation, we consider the semilinear equation \begin{align} \label{liouvilleequationab} Δu=G(u) \qu…
On location of maximum of gradient of torsion function
Qinfeng Li, Ruofei yao
It has been a widely belief that for a planar convex domain with two coordinate axes of symmetry, the location of maximal norm of gradient of torsion function is either linked to c…
Concentration breaking on two optimization problems
Yong Huang, Qinfeng Li, Qiuqi Li
In the present paper, we study the boundary concentration breaking phenomena on two thermal insulation problems considered on Lipschitz domains, based on Serrin's overdetermined re…
Some geometric inequalities related to Liouville equation
Changfeng Gui, Qinfeng Li
In this paper, we prove that if is a solution to the Liouville equation \begin{align} \label{scalliouville} Δu+e^{2u} =0 \quad \mbox{in ,} \end{align}then the dia…
