Class number for pseudo-Anosovs
François Dahmani, Mahan Mj
Given two automorphisms of a group , one is interested in knowing whether they are conjugate in the automorphism group of , or in the abstract commensurator of , and how t…
Mixing Properties of Stable Random Fields Indexed by Amenable and Hyperbolic Groups
Mahan Mj, Parthanil Roy, Sourav Sarkar
We show that any stationary symmteric -stable () random field indexed by a countable amenable group is weakly mixing if and only if it is generated by a null action, ex…
The Gromov-Tischler theorem for stratified spaces
Mahan Mj, Balarka Sen
We define a notion of a symplectic structure on stratified spaces, and demonstrate that given a symplectic structure on a stratified space with integral cohomology class, c…
h-Principle for Stratified Spaces
Mahan Mj, Balarka Sen
We extend Gromov and Eliashberg-Mishachev's h-principle on manifolds to stratified spaces. This is done in both the sheaf-theoretic framework of Gromov and the smooth jets framewor…
Commensurators of normal subgroups of lattices
David Fisher, Mahan Mj, Wouter Van Limbeek
We study a question of Greenberg-Shalom concerning arithmeticity of discrete subgroups of semisimple Lie groups with dense commensurators. We answer this question positively for no…
