   Title: Nonpositively Curved Cube Complexes in Geometric Group Theory

Abstract: 
Nonpositively curved cube complexes have come to occupy an increasingly
important role in geometric group theory. Surprisingly many of the groups
traditionally studied by combinatorial group theorists are turning out
to act properly on CAT(0) cube complexes. This is leading to an increased
and more unified understanding of these groups, as well as the resolution
of some of the algebraic problems that were first raised in combinatorial
group theory but were unapproachable without geometric methods. We will
survey groups acting on CAT(0) cube complexes with an eye towards these
recent developments.
