Symmetry And Tiling Groups For Genus 4 And 5, C. Ryan Vinroot
Symmetry And Tiling Groups For Genus 4 And 5, C. Ryan Vinroot
Mathematical Sciences Technical Reports (MSTR)
All symmetry groups for surfaces of genus 2 and 3 are known. In this paper, we classify symmetry groups and tiling groups with three branch points for surfaces of genus 4 and 5. Also, a class of symmetry groups that are not tiling groups is presented, as well as a class of odd order non-abelian tiling groups.
Quadrilaterals Subdivided By Triangles In The Hyperbolic Plane, Dawn M. Haney, Lori T. Mckeough
Quadrilaterals Subdivided By Triangles In The Hyperbolic Plane, Dawn M. Haney, Lori T. Mckeough
Mathematical Sciences Technical Reports (MSTR)
In this paper, we consider triangle-quadrilateral pairs in the hyperbolic plane which “kaleidoscopically” tile the plane simultaneously. These tilings are called divisible tilings or subdivided tilings. We restrict our attention to the simplest case of divisible tilings, satisfying the corner condition, in which a single triangle occurs at each vertexof the quadrilateral. All possible such divisible tilings are catalogued as well as determining the minimal genus surface on which the divisible tiling exists. The tiling groups of these surfaces are also determined.

A central question in the area of topological graph theory is to find the genus of a given graph. In particular, the genus parameter has been studied for Cayley graphs. A Cayley graph is a representation of a group and a fixed generating set for that group. A group is said to be planar if there is a generating set which produces a planar Cayley graph. We say that a group is toroidal if there is a generating set that produces a toroidal Cayley graph and if there are no generating sets which produce a planar Cayley graph. Characterizations for …

Pseudocontinuations And The Backward Shift, William T. Ross, Alexandru Aleman, Stefan Richter
Department of Math & Statistics Faculty Publications
In this paper, we will examine the backward shift operator Lf = (f −f(0))/z on certain Banach spaces of analytic functions on the open unit disk D. In particular, for a (closed) subspace M for which LM Ϲ M, we wish to determine the spectrum, the point spectrum, and the approximate point spectrum of L│M. In order to do this, we will use the concept of “pseudocontinuation" of functions across the unit circle T.
We will first discuss the backward shift on a general Banach space of analytic functions and then for the weighted …
Chief Factors And The Principal Block Of A Restricted Lie Algebra, Jorg Feldvoss
Chief Factors And The Principal Block Of A Restricted Lie Algebra, Jorg Feldvoss
University Faculty and Staff Publications
This paper is part of the conference proceedings from the conference titled The Monster and Lie Algebras that took place during a special research quarter at the Ohio State University in the spring of 1996. This conference was sponsored by the Ohio State University Mathematical Research Institute and the National Science Foundation. The focus of the conference was groups, Lie algebras, and the Monster, with emphasis on presenting the various aspects of group theory and Lie algebra theory from a modern perspective.
