Dubi Kelmer (Boston College) gives this seminar. Welcome!

Abstract: In this talk I will describe new results establishing the existence of a strong spectral gap for any geometrically finite, n dimensional, hyperbolic manifold with critical exponent greater than (n-1)/2. This settles a conjecture of Mohammadi and Oh from 2015.

This is based on joint work with Osama Kahlil and Pratyush Sarkar.

This is a seminar in our seminar series on Dynamical Systems and Number Theory (DSNT).
