Cube complexes


Daniel Wise

McGill University



CAT(0) cube complexes are high-dimensional generalizations of trees that have emerged as increasingly central objects in infinite group theory. I will indicate their most prominent geometric properties and describe some of their appearances within mathematics and then explain how these cube complexes arise from infinite groups.
