报告题目1:Local properties of positive solutions to elliptic equations with some singular potential
报告人:魏雷教授
报告摘要:
In this talk, we firstly show that uniqueness and exact behavior of positive solutions to the elliptic equations when the potential function is Hardy potential and the parameter is supercritical. Secondly, we will give some results of positive solutions to the elliptic equations when the potential function has strong singularity. Finally, we will give some boundary property of positive solutions to elliptic equations with other type of potential.

报告题目3:Liouville Type Theorem for Some Nonlocal Elliptic Equations
报告人:余晓辉副教授
报告摘要:
In this talk, we will introduce some Liouville theorems for elliptic equations with nonlocal nonlinearities. Because of the nonlocal nonlinearities, it is not easy to apply the moving plane method directly. Moreover, since the nonlinearity is only assumed to be continuous, the classical maximum principles cannot be applied. To overcome our difficulties, we turn the equation into an integral-differential system, then we use the moving plane method in an integral form to prove our results.  Moreover, we raised the nonlocal boundary value condition for the first time.
