Princeton/IAS Symplectic Geometry Seminar

Topic: Critical toric surfaces and applications

Speaker: Weiwei Wu

Date & Time: Monday February 12th, 2018, 4:00pm - 7:00pm

Location: Fine Hall 322, Princeton University

We introduce the notion of critical toric surfaces, with a focus on the so-call "critical toric blow-ups". These are symplectic manifolds with a toric action on the complement of an isotropic Lagrangian skeleton.  We explain some applications of this construction on new constructions of finite group actions; understanding the symplectic mapping class groups; and the construction of Lagrangian torus fibrations. This is joint work with Liat Kessler.
