Groups of piecewise isometric permutations of lattice points or finitary rearrangements of tessellations
Robert Bieri, Heike Sach
Through the glasses of didactic reduction: We consider a (periodic) tessellation of either Euclidean or hyperbolic -space . By a piecewise isometric rearrangement of …

FPn properties of generalized Houghton groups
Heike Sach
This Thesis presents a 2-dimensional generalization of Houghtons' groups H_n. H_n is defined to be the group of all permutations p of a disjoint union of copies of the natural numb…

Groups of piecewise isometric permutations of lattice points
Robert Bieri, Heike Sach
Let M denote either Euclidean or hyperbolic n-space, and let G be a discrete group of isometries of M, with the property that G respects and acts tile-transitively on a convex-poly…
