Abstract: A lattice in a locally compact group G is a discrete subgroup of cofinite volume. Lattices in Lie groups are well-studied, but little is known about lattices in other, "exotic", locally compact groups. Examples of exotic groups include isometry groups of trees, buildings, polyhedral complexes and CAT(0) spaces, and Kac-Moody groups. We will survey known results, which include both rigidity and surprising examples of flexibility, and discuss the wide range of tools used to investigate lattices in these non-classical settings.
The Colloquium will be followed by a reception for our speaker in
the Staff Tea Room with wine and nibbles to which all are invited.
