Title

:

Horocycles on the modular surface and diophantine approximation

Abstract

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.
