SUMMARY:Extremal rays, Gromov-Witten invariants, and rationally connected varieties
DESCRIPTION:Speaker: Zhiyu Tian\, California Institute of Technology\n\nThis work is motivated by Kollár's conjecture on symplectic deformation invariance of rational connectedness and "symplectic birational geometry". I will discuss some simple observations which seem to suggest that extremal rays of the Mori cone deform together with the deformation of the variety as …
