High dimensional hyperbolic Coxeter groups that virtually fiber (Jean-François Lafont, Ohio State University)

19.06.2025 10:30

I'll explain how to construct hyperbolic Coxeter groups that virtually algebraically fiber (i.e. surject to Z with a finitely generated kernel), and that have arbitrarily high virtual cohomological dimension. Prior examples were only known to exist up to dimension eight. This is joint work with Minemyer, Sorcar, Stover, and Wells.
