Cohn-Vossen theory for locally conformally flat manifolds
Shiguang Ma
We establish a refined singularity estimate for nonnegative n-superharmonic functions. For complete noncompact locally conformally flat manifolds with nonnegative Ricci curvature,…

Isolated singularities of solutions of certain quasi-linear elliptic inequalities
Shiguang Ma, Shengyang Zang
We provide a complete classification of the asymptotic behavior of isolated singularities for solutions satisfying \[ 0\le-Î_{p}u(x)\le Ïu^{\frac{n(p-1)}{n-p}} (x),\,\,u(x)\ge0,\…

-Laplacian and -Hessian type equations with exponential reaction term and measure data
Shiguang Ma, Zijian Wang
In this article, we will prove existence results for the equations of the type and in a bounded domain , with Dirichlet…
