Cubical Dimension Of Groups

Abstract

The cubical dimension of a group G is the infimum n such that G admits a proper action on an n-dimensional CAT(0) cube complex. 

I will discuss some examples of groups with a gap between its cubical dimension and its cohomological or CAT(0) dimension. 

This will include a construction of small cancellation groups with arbitrarily large cubical dimension.
