Examples of finitely presented groups with strong fixed point properties and property (T)
Indira Chatterji, Martin Kassabov
We construct a finitely presented group with property (T) which can not act on on reasonable spaces. Such group is constructed using an generalization of Hall embedding theorem, wh…
On the Idempotent Conjecture for Sidki Doubles
Indira Chatterji, Guido Mislin
Let be a group and its Sidki Double. The idempotent conjecture says that there should be no non-trivial idempotent in the complex group ring of a torsion-free group. We…
Horospherical random graphs and lockdown strategies
Indira Chatterji, Austin Lawson
Expanders are sparse graph that are strongly connected, where {\it connectivity} is quantified using eigenvalues of the adjacency matrix, and {\it sparsity} in terms of vertex vale…
The first -Betti number and groups acting on trees
Indira Chatterji, Sam Hughes, Peter Kropholler
We generalise results of Thomas, Allcock, Thom-Petersen, and Kar-Niblo to the first -Betti number of quotients of certain groups acting on trees by subgroups with free acti…
Tangent bundles of hyperbolic spaces and proper affine actions on spaces
Indira Chatterji, François Dahmani, Thomas Haettel +1
We define the notion of a negatively curved tangent bundle of a metric measured space. We prove that, when a group acts on a metric measured space with a negatively curved…
Proper actions on spaces for relatively hyperbolic groups
Indira Chatterji, François Dahmani
We show that for any group that is hyperbolic relative to subgroups that admit a proper affine isometric action on a uniformly convex Banach space, then acts properly on a…
