Groups of piecewise isometric permutations of lattice points, or Finitary rearrangements of tessellations
- Through the glasses of didactic reduction, we consider a (periodic) tessellation Ξ of either Euclidean or hyperbolic π-space π. By a piecewise isometric rearrangement of Ξ we mean the process of cutting π along corank-1 tile-faces into finitely many convex polyhedral pieces, and rearranging the pieces to a new tight covering of the tessellation Ξ. Such a rearrangement defines a permutation of the (centers of the) tiles of Ξ, and we are interested in the group of ππΌ(Ξ) all piecewise isometric rearrangements of Ξ. In this paper, we offer (a) an illustration of piecewise isometric rearrangements in the visually attractive hyperbolic plane, (b) an explanation on how this is related to Richard Thompson's groups, (c) a section on the structure of the group pei(β€π) of all piecewise Euclidean rearrangements of the standard cubically tessellated βπ, and (d) results on the finiteness properties of some subgroups of pei(β€π).
