Seminars and Colloquia by Series

Lagrangian Floer Theory I

Series
Geometry Topology Working Seminar
Time
Friday, March 10, 2017 - 14:00 for 1.5 hours (actually 80 minutes)
Location
Skiles 006
Speaker
John Etnyre – Georgia Tech

Please Note: This will be a 1.5 hour seminar.

Following up on the previous series of talks we will show how to construct Lagrangian Floer homology and discuss it properties.

Building Morse/Floer type homology theories III

Series
Geometry Topology Working Seminar
Time
Friday, February 17, 2017 - 14:00 for 1 hour (actually 50 minutes)
Location
Skiles 006
Speaker
John Etnyre – Georgia Tech

Please Note: Note todays seminar is just form 2 to 3 to accomodate a seminar at 3.

In this series of talks I will descibe a general proceedure to construct homology theories using analytic/geometric techiques. We will then consider Morse homology in some detail and a simple example of this process. Afterwords we will consider other situations like Floer theory and possibly contact homology.

Legendrian Contact Homology

Series
Geometry Topology Working Seminar

Speaker
John Etnyre – Georgia Tech
I will give 2 or 3 lectures on Legendrian contact homology. This invariant has played a big role in our understanding of Legendrian submanifolds of contact manifolds in all dimensions. We will discuss the general definition but focus on the 3-dimensional setting where it easiest to compute (and describe Legendrian knots). I will also discuss the A^\infty structure associated to the linearized co-chain groups of contact homology.

Notions of knot concordance II

Speaker
Jennifer Hom – Georgia Tech
The knot concordance group consists of knots in the three-sphere modulo the equivalence relation of smooth concordance. We will discuss two concordance invariants coming from knot Floer homology: tau and epsilon.
