Title:
Fragmentation pseudo-metrics and Lagrangian submanifolds
Speaker:
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.
