Lattices in exotic groups |
Abstract |
Lattices in Lie groups are well-studied, but little is known about lattices in other locally compact groups. Examples of such “exotic” groups include isometry groups of trees, polygonal 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. |
