Topology Seminar

Tue., Sep. 28, 2021 3:00 p.m.

Location: Live Stream

Speaker: Tse Leung So, University of Regina

Title: Stasheff associahedra, A_{infinity} spaces and loop spaces

Zoom: https://uregina-ca.zoom.us/j/99127226830?pwd=bnFQR1R3UUdyWUxqSS9JMExMRlZwZz09

Abstract:  

A loop space is a good example of an A_{infinity} space as its multiplication is not strictly associative but only associative up to coherent homotopy. In this seminar I will talk about the Stasheff associahedra, A_{infinity} spaces and the recognition principle for loop spaces.
