    • Collapsibility and Z-Compactifications of CAT(0) Cube Complexes 

      Gulbrandsen, Daniel L (2023-08-01)
      We extend the notion of collapsibility to non-compact complexes and prove collapsibility of locally-finite CAT(0) cube complexes. Namely, we construct such a cube complex $X$ out of nested convex compact subcomplexes ...
