Vanishing of cohomology with coefficients in representations on Banach spaces of groups acting on Buildings
Izhar Oppenheim
We prove vanishing of cohomology with coefficients in representations on a large class of Banach spaces for a group acting "nicely" on a simplicial complexes based on spectral prop…

Averaged projections, angles between groups and strengthening of property (T)
Izhar Oppenheim
Using the method of averaged projections and introducing a new notion of angles between projections, we establish a criterion for a certain type of strengthening of property (T) (w…

Isoperimetric Inequalities and topological overlapping for quotients of Affine buildings
Izhar Oppenheim
We prove isoperimetric inequalities for quotients of -dimensional Affine buildings. We use these inequalities to prove topological overlapping for the 2-dimensional skeletons of…
