Cobordism maps in knot Floer homology

Presented by: 
Andras Juhasz University of Oxford
Tuesday 31st January 2017 - 14:00 to 15:00
INI Seminar Room 1
Decorated knot cobordisms functorially induce maps on knot Floer homology.
We compute these maps for elementary cobordisms, and hence give a formula for 
the Alexander and Maslov grading shifts. We also show a non-vanishing result in the case of
concordances and present some applications to invertible concordances. 
This is joint work with Marco Marengon.

We'll get it fixed as soon as possible.
