Geometric dimension of lattices in classical simple Lie groups
Javier Aramayona, Dieter Degrijse, Conchita Martinez-Perez +1
We prove that if is a lattice in a classical simple Lie group , then the symmetric space of is -equivariantly homotopy equivalent to a proper cocompact -CW complex…

Bredon cohomological dimensions for groups acting on CAT(0)-spaces
Dieter Degrijse, Nansen Petrosyan
Let G be a group acting isometrically with discrete orbits on a separable complete CAT(0)-space of bounded topological dimension. Under certain conditions, we give upper bounds for…
