Liouville theorems for conformal -curvature equations
Meiqing Xu, Hui Yang
In this paper, we study the non-existence of positive solutions for the following conformal -curvature equation \begin{equation*} (-Î)^Ïu = K(x) u^{\frac{n+2Ï}{n-2Ï}} \quad…
On isolated singularities of the conformal Gaussian curvature equation and -curvature equation
Hui Yang, Ronghao Yang
In this paper, we study the isolated singularities of the conformal Gaussian curvature equation \[ -Îu = K(x) e^{u} \quad ~ in ~ B_{1} \setminus \{ 0 \}, \] where $B_1 \setminus \…
The direct moving sphere for fractional Laplace equation
Congming Li, Meiqing Xu, Hui Yang +1
This paper works on the direct method of moving spheres and establishes a Liouville-type theorem for the fractional elliptic equation \[ (-Î)^{α/2} u =f(u) ~~~~~~ \text{in } \mat…
