Title: Homotopy invariant algebraic structure

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

Abstract:  

Homotopy invariance is an important property not satisfied by all operads. In our talk, we give counterexamples and discuss some examples involving A-infinity operads in topological spaces and A-infinity algebras in chain complexes.
