Arithmetic Reflection Groups and Congruence
Abstract: It was recently shown that there are only finitely many maximal arithmetic
hyperbolic reflection groups. In this talk, I will discuss work to
identify some of these groups by finding the corresponding polyhedra and
generating isometries. This leads to finding examples which are not
congruence, answering a question of Agol, Belolipetsky, Storm and Whyte.
