Location
ONLINE
Speaker
Tyrone Ghaswala – CIRGET, Université du Québec à Montréal –

This pre-talk will be an introduction to infinite-type surfaces and big mapping class groups. I will have a prepared talk, but it will be extremely informal, and I am more than happy to take scenic diversions if the audience so desires!

Algebraic definitions for string topology

Speaker
Kate Poirier – CUNY - City College of Technology –

String topology studies various algebraic structures given by intersecting loops in a manifold, as well as those on the Hochschild chains or homology of an algebra. In this preparatory talk, we survey a collection of such structures and their relationships with one another.

Pre-talk for "The coalgebra of singular chains and the fundamental group"

Speaker
Manuel Rivera – Purdue –

In the first talk I will introduce the main constructions, many of which are classical, from scratch. This part will be introductory and accessible to a general audience with a basic knowledge of topology. This introduction will also serve as preparation for the main talk in which I will outline the proof and discuss some applications.

Knot Floer homology

Location
Skiles 006
Speaker
Tom Hockenhull – University of Glasgow

I’ll try and give some background on the definition of knot Floer homology, and perhaps also bordered Heegaard Floer homology if time permits.
