Outer automorphism groups and the Atiyah Conjecture
Sam P. Fisher, Andrew Ng
Let be the fundamental group of a compact surface, a finitely generated free group, or more generally a finitely generated right-angled Artin group. We prove that the von Neuma…
Coherent RFRS groups
Sam P. Fisher, Marco Linton, Pablo Sánchez-Peralta
We prove that a finitely generated virtually RFRS group of cohomological dimension at most is coherent if and only if its second -Betti number vanishes if and only if it…
Division rings for group algebras of virtually compact special groups and -manifold groups
Sam P. Fisher, Pablo Sánchez-Peralta
Let be a division ring and let be either a torsion-free virtually compact special group or a finitely generated torsion-free -manifold group. We embed the group algebra…
Homological growth of Artin kernels in positive characteristic
Sam P. Fisher, Sam Hughes, Ian J. Leary
We prove an analogue of the Lück Approximation Theorem in positive characteristic for certain residually finite rationally soluble (RFRS) groups including right-angled Artin groups…
Improved algebraic fibrings
Sam P. Fisher
We show that a virtually RFRS group of type virtually algebraically fibres with kernel of type if and only if the first…
