Positive solutions for non local elliptic problems
Jinggang Tan
We establish existence and regularity results, as well as a priori estimates of Gidas-Spruck type for nonlinear problems involving the fractional power of the Dirichlet Laplacian.

A Harnack inequality for fractional Laplace equations with lower order terms
Jinggang Tan Jingang Xiong
We establish a Harnack inequality of fractional Laplace equations without imposing sign condition on the coefficient of zero order term via the Moser's iteration and John-Nirenberg inequality.

Youyan Wan Jinggang Tan

We show the existence of nontrivial solutions to Chern-Simons-Schrödinger systems by using the concentration compactness principle and the argument of global compactness.
