Abstract:

A CAT(0) cube complex is a higher dimensional version of a tree.

An interesting geometric feature of a CAT(0) cube complex is the existence

of codimension 1 hyperplanes that separate points in the 0-skeleton of the

complex. We discuss a canonical procedure by which one can reconstruct a

CAT(0) cube complex from a system of separating hyperplanes.
