### Joint UGA/Tech Topology Seminar at UGA: Concordance invariants from branched coverings and Heegaard Floer homology

- Series
- Geometry Topology Seminar
- Time
- Monday, November 18, 2019 - 14:30 for 1 hour (actually 50 minutes)
- Location
- Boyd 221
- Speaker
- Antonio Alfieri – UBC

I will outline the construction of some knot concordance invariants based on the Heegaard Floer homology of double branched coverings. The construction builds on some ideas developed by Hendricks, Manolescu, Hom and Lidman. This is joint work with Andras Stipsicz, and Sungkyung Kang.
