Speaker: Zhi-Qiang Wang (Utah State University and Nankai University

Venue: Room 09 at Quan-Zhai (全斋), New location for BICMR, Peking University

Time: March 30, 2012, Friday, 10:30-11:30am

Abstract: In this talk, we discuss recent work on existence of multiple positive solutions for a class of nonlinear elliptic systems in attractive and repulsive cases. The methods are bifurcation analysis and variational methods.
