Cluster machinery and applications


Abstract

This is based on joint work with Francois Lalonde. The cluster complex is a construction whose purpose is to manage algebraically the bubbling of disks in Lagrangians. I will discuss in this talk some aspects of this construction as well as some related conjectures and applications.
