What is ... a group action?

This page hosts information on Mikola Lysenko's talk "What is ... a group action?" at the "What is ...?" seminar. The talk will take place on Friday, June 8, 1:00pm at the BMS Loft at Urania. This talk will help you better understand the talk by Karen Vogtmann, which will start at 2pm.

We will again be ordering delivery pizza. If you would like to order pizza with us, please arrive to the "What is ...?" seminar by 12:45pm.


This short expository talk is an attempt to answer the "What?" and "Why?" of group theory. Because no familiarity with abstract algebra is assumed, we will start from first principles in order to keep this presentation self contained. The main goal here is to impart some conceptual understanding, not to study any single problem in much depth. We will focus on motivation, and survey a few interesting applications.
