Joint equidistribution of maximal flat cylinders and holonomies in Anosov homogeneous spaces [3]
03/02/2023 - 4:00pm

 Margulis–Mohammadi–Oh (‘14) described the asymptotic joint equdistribution of the closed geodesics and holonomies of a geometrically finite rank one locally symmetric manifold as their lengths grow to infinity.
 We obtain an Anosov analogue of this result. More precisely,  in the quotient of a higher rank semisimple Lie group by an  Anosov subgroup, non-trivial closed orbits under a maximal real-split torus give rise to maximal flat cylinders. We prove an analogous joint equidistribution result of the maximal flat cylinders and holonomies with circumferences growing to infinity. 

This is joint work with Elijah Fromm.

Recent results in elliptic homogenization. [4]
03/02/2023 - 4:00pm

I will discuss some recent results and open problems in elliptic homogenization. This will include my work with Armstrong and Kuusi on large scale regularity for solutions of periodic operators
