Fixed point properties and cohomology of Banach representations of arithmetic groups
Saar Bader, Shaked Bader, Uri Bader +1
We study fixed point theorems for actions of lattices of semisimple groups. They are deduced from vanishing results for the group cohomology of -representations. We show that…
Quasiisometric embeddings between right-angled Artin groups: flexibility
Shaked Bader, Oussama Bensaid, Harry Petyt
We give a complete characterisation of when the right-angled Artin group on one cycle graph can be quasiisometrically embedded in the right-angled Artin group on another cycle grap…
Quasiisometric embeddings between right-angled Artin groups: rigidity
Shaked Bader, Oussama Bensaid, Harry Petyt
By introducing branching conditions on the defining graph, we prove a range of rigidity results for quasiisometric embeddings between right-angled Artin groups. The starting point…
From branching quasiflats to flats in CAT(0) cube complexes
Shaked Bader, Oussama Bensaid, Harry Petyt
We study quasiisometric embeddings between finite-dimensional CAT(0) cube complexes. More specifically, we introduce geometric branching conditions under which flats in the domain,…
Subgroups of word hyperbolic groups in dimension 2 over arbitrary rings
Shaked Bader, Robert Kropholler, Vladimir Vankov
In 1996, Gersten proved that finitely presented subgroups of a word hyperbolic group of integral cohomological dimension 2 are hyperbolic. We use isoperimetric inequalities over ar…
CAT(0) Polygonal Complexes are 2-Median
Shaked Bader, Nir Lazarovich
Median spaces are spaces in which for every three points the three intervals between them intersect at a single point. It is well known that rank-1 affine buildings are median spac…
