Abstract

Zoom Link

I will review old and new results, by various authors, on the distribution of smallest denominators of rational numbers in a shrinking interval (as well as higher-dimensional variants) and explore the connection to extreme value laws in homogeneous dynamics, specifically horocycle flows. This lecture is in part based on joint work with Mark Pollicott.
