[Binghamton Geometry Topology Seminar] Geometry and Topology seminar: Jonathan Williams

[Cary Malkiewich]

Hi everyone,

This week we are pleased to have our very own Jonathan Williams talking
about smooth 4-manifolds, title and abstract below. As usual, the talk will
be on Thursday at 2:50pm in WH 100E.

The "seminar lunch" will again be at the picnic table just outside the main
entrance a little after 12pm (in case you need to go pick up food and bring
it back). Anyone is welcome to join!

Best,
Cary

=========================================
Title: Turning a Lefschetz fibration into a crown map
Abstract: A rich source of examples of smooth 4-manifolds comes from
finding a composition of Dehn twists on a closed surface which is isotopic
to the identity map. I'll describe how to turn this into a source of
examples of crown diagrams of smooth 4-manifolds.
