Vanishing cycles and exceptional collections

on Friday, February 22, at 11:00, at room C of SISSA Main Building



Abstract

We prove that the Euler characteristic pairing  evaluated on the  
classes of the elements on an exceptional collection on a  minimal  
Fano threefold coincides with the intersection pairing on vanishing  
cycles in the Landau-Ginsburg
model of F.
