"Prime matrices, lattice points and ergodic theorems"

** Abstract: **

Consider the following two questions :
- Are there infinitely many 2 x 2 integral matrices of
determinant 2 all of whose elements are prime numbers ?
- If so, how many such matrices one should expect to find in ball
of radius T in the space of 2 x 2 matrices ?

We will explain an approach towards these questions,
via sieve methods, non-Euclidean lattice point problems,
and ergodic theorems on Lie groups.
Based on joint work with Peter Sarnak.

Light refreshments will be served in the faculty lounge at 3:30.
