Boundaries of Baumslag-Solitar Groups
Craig R. Guilbault, Molly A. Moran, Carrie J. Tirel
A -structure on a group was introduced by Bestvina in order to extend the notion of a group boundary beyond the realm of CAT(0) and hyperbolic groups. A refinement…
Proper homotopy types and Z-boundaries of spaces admitting geometric group actions
Craig R. Guilbault, Molly A. Moran
We extend several techniques and theorems from geometric group theory so that they apply to geometric actions on arbitrary proper metric ARs (absolute retracts). A second way that…
Slice Implies Mutant Ribbon for Odd, 5-Stranded Pretzel Knots
Kathryn A. Bryant
A pretzel knot is called if all its twist parameters are odd, and if it is mutant to a simple ribbon knot. We prove that the family of odd, 5-stranded p…
Noncompact manifolds that are inward tame
Craig R. Guilbault, Frederick C. Tinsley
We continue our study of ends of non-compact manifolds, with a focus on the inward tameness condition. For manifolds with compact boundary, inward tameness, has significant implica…
Spherical alterations of handles: embedding the manifold plus construction
Craig R. Guilbault, Frederick C. Tinsley
A key tool in our earlier work on ends of manifolds high-dimensional manifolds was an ability to embed cobordisms provided by the Quillen Plus Construction into those ends. Here we…
Manifolds with non-stable fundamental groups at infinity, III
Craig R Guilbault, Frederick C Tinsley
We continue our study of ends non-compact manifolds. The over-arching aim is to provide an appropriate generalization of Siebenmann's famous collaring theorem that applies to manif…
