Geometric Group Theory and Untangling Ear-Phones

Neha Gupta (University of Illinois at Urbana-Champaign)

Abstract: Suppose you get your ear-phones entangled around a doughnut with two holes... an entirely probable scenario! Then how "big" does your doughnut need to be to in order for you to successfully untangle your ear-phones? This is going to be a gentle introduction to groups, and how they connect to geometry. We will slowly build up to answering our original question. This is joint work with Ilya Kapovich.
