Abstract of the Lecture:
In this talk, we firstly introduce some recent international developments on entire blow-up solutions for semilinear and quasilinear Schrödinger elliptic systems.Then weshow some new results on the existence and nonexistence of radial large positive solutions for modified Schrödinger systems with a nonconvex diffusion term by a successive iteration technique and the dual approach. The necessary and sufficient condition for the existence of radial large positive solutions is established.
