Stability in Topology, Arithmetic, and Representation Theory 2023

General Information

The focus of the conference is on homological stability, representation stability, and related ideas. Our goal is to bring together early-career researchers working in these areas as well as to bring new people into this exciting field.

This conference will be hybrid. Please register to participate in-person or online (using Microsoft Teams). The organizers highly encourage participants to come in-person if possible as networking and collaboration is generally easier in-person.

Please email the organizers if you would like to attend online and have not received the Teams link yet.
