Title:
Fragmentation pseudo-metrics and Lagrangian submanifolds

Speaker:
Octav Cornea

Abstract:
The purpose of the talk is to discuss a class of pseudo-metrics that can be defined on the set of objects of a triangulated category whose morphisms are endowed with a notion of weight. In case the objects are Lagrangian submanifolds (possibly immersed) there are a some natural ways to define such pseudo-metrics and, if the class of Lagrangian submanifolds is unobstructed, these pseudo-metrics are non-degenerate and extend in a natural way the Hofer distance. The talk is based on joint work with P. Biran and with E. Shelukhin.
