Arithmetic on Markoff Surfaces
Daniel Martin
4:30pm|Simonyi 101

The generalized Markoff equation gives rise to a dynamical system via the Markoff group acting on the solution set. This talk considers the resulting dynamics over finite fields, which has strong connections with combinatorial group theory and...
