Property (T) is a powerful property of groups, with many useful
consequences. Probably the best known examples of groups with (T) are
higher rank lattices. In this talk I will provide a proof
that for n ≥ 3, SLn(ℤ) has (T). A nice feature of the
approach I will follow is that it works entirely within the world of
discrete groups: this is in contrast to the classical method, which
relies on being able to embed a group as a lattice
in an ambient Lie group.
