Speaker: Dr. Jayadev Athreya, Yale University

Time: 4:00 p.m.
Venue: Lecture Hall - I, Dept. of Mathematics
We describe a relationship between cusp excursions of horocycles on the modular surfaces SL(2, R)/SL(2, Z) and diophantine approximation. Some of the work we discuss will be joint with G. Margulis, and some joint with Y. Cheung
