About:
Artin groups form an important class of groups that generalise braid groups. While many problems about these groups remain open in general, our understanding of the structure and geometry of Artin groups has seen dramatic advances in recent years. This workshop will bring together mathematicians working on general Artin groups from various perspectives (actions in non-positive curvature, Garside structures, algorithmic aspects, combinatorics, etc.) to encourage new interactions and collaborations.
Arrangements
Thursday 20 May: Joining instructions have been sent to all registered speakers and participants. If you have not recevied an email from Jane Walker at ICMS please check your spam folder.
Each day will begin with a talk in Zoom at 14.00 BST, with breaks using Gather.Town. In addtion there will be discussion sessions on Tuesday, Wednesday and Thursday.
Gather.Town is a video-calling space that lets multiple people hold separate conversations in parallel, walking in and out of those conversations as if they might do in an in-person meeting. Gather.Town looks like a retro video game and is very easy to navigate. A drop in session for Gather. Town will be held on Friday 21 May so that participants can test the space out for themselves.
