Trisections and low-dimensional topology
March 20 to March 24, 2017
American Institute of Mathematics, San Jose, CA

Organizers:
David Gay, Robion Kirby, Jeffrey Meier, and Alexander Zupan

Description:
This workshop, sponsored by AIM and the NSF, will be devoted to
a new perspective on 4-dimensional topology introduced by Gay and
Kirby in 2012: 
Every smooth 4-manifold can be decomposed into three simple pieces
via a trisection, a generalization of a Heegaard splitting of a
3-manifold. The theory of trisections has expanded to include the
relative settings of surfaces in 4-manifolds and 4-manifolds with
boundary, and tantalizing evidence reveals that trisections may
bridge the gap between 3- and 4-dimensional topology. 

Deadline:
