The Combinatorial Topology of Groups
Brent Everitt
This is the first installment of a book on combinatorial and geometric group theory from the topological point of view. This is a classical subject. The installment contains Chapte…
Weyl groups, lattices and geometric manifolds
Brent Everitt, Robert B. Howlett
By studying the action of the Weyl group of a simple Lie algebra on its root lattice, we construct torsion free subgroups of small and explicitly determined index in a large infini…
Homology of coloured posets: a generalisation of Khovanov's cube construction
Brent Everitt, Paul Turner
We define a homology theory for a certain class of posets equipped with a representation. We show that when restricted to Boolean lattices this homology is isomorphic to the homolo…
Graphs, free groups and the Hanna Neumann conjecture
Brent Everitt
A new bound for the rank of the intersection of finitely generated subgroups of a free group is given, formulated in topological terms, and very much in the spirit of Stallings. Th…
