Orders and Fibering
Boris Okun, Kevin Schreve
In 2018, Kielak gave a virtual fibering criterion for RFRS groups. In this paper, we present a simpler proof of this.
Torsion invariants of complexes of groups
Boris Okun, Kevin Schreve
Suppose a residually finite group acts cocompactly on a contractible complex with strict fundamental domain , where the stabilizers are either trivial or have normal $\mathb…
Mod and torsion homology growth in nonpositive curvature
Grigori Avramidi, Boris Okun, Kevin Schreve
We compute the mod homology growth of residual sequences of finite index normal subgroups of right-angled Artin groups. We find examples where this differs from the rational ho…
Growth series of CAT(0) cubical complexes
Boris Okun, Richard Scott
Let be a CAT(0) cubical complex. The growth series of at is , where denotes -distance between and .…
The Atiyah conjecture for the Hecke algebra of the infinite dihedral group
Boris Okun, Richard Scott
We prove a generalized version of the Strong Atiyah Conjecture for the infinite dihedral group W, replacing the group von Neumann algebra NW with the Hecke-von Neumann algebra N_qW…
Cohomology computations for Artin groups, Bestvina-Brady groups, and graph products
Michael W. Davis, Boris Okun
We compute: * the cohomology with group ring coefficients of Artin groups (or actually, of their associated Salvetti complexes), Bestvina-Brady groups, and graph products of groups…
