Event № 790
In this talk I will introduce a procedure to produce interesting examples of non-positively curved cube complexes. The construction we suggest takes as input two finite simplicial complexes and gives as output a finite cube complex whose local geometry can be easily described. This local information can then be used to obtain global information, e.g. about cohomological dimension and hyperbolicity of the fundamental group of the cube complex. This is joint work with Robert Kropholler.
