Exponential growth rates of even Coxeter groups
Véra Bossart, Michelle Bucher
Let be an even Coxeter group. We prove that among all Coxeter systems generating the unique even Coxeter system realizes the minimal exponential growth. Our proof relies on…

Kernels in measurable cohomology for transitive actions
Michelle Bucher, Alessio Savini
Given a connected semisimple Lie group , Monod has recently proved that the measurable cohomology of the -action on the Furstenberg boundary $…
