NPC - Non-positive curvature group actions and cohomology

Ozawa found a new characterization of property (T) of finitely generated groups. His theorem gives an algorithm to compute a lower bound of the Kazhdan constant. Netzer-Thom actually found a good positive lower bound for SL(3,Z). I will report on computer experiments on other examples. We found good lower bounds for lattice groups on A2-tilde buildings, which have property (T). This is an experimental math talk.
