Generating Functions for Hyperbolic Plane Tessellations

Xie, Jiale (University of Waterloo, 2017-08-28)

For a hyperbolic plane tessellation there is a generating function with respect to the distance. This generating function is the same as the growth function of a group of isometries of hyperbolic plane that acts regularly ...
Ordinary and Generalized Circulation Algebras for Regular Matroids

Olson-Harris, Nicholas (University of Waterloo, 2018-09-19)

Let E be a finite set, and let R(E) denote the algebra of polynomials in indeterminates (x_e)_{e in E}, modulo the squares of these indeterminates. Subalgebras of R(E) generated by homogeneous elements of degree 1 have ...
Results on Chromatic Polynomials Inspired by a Correlation Inequality of G.E. Farr

McKay, Ghislain (University of Waterloo, 2018-09-25)

In1993 Graham Farr gave a proof of a correlation inequality involving colourings of graphs. His work eventually led to a conjecture that number of colourings of a graph with certain properties gave a log-concave sequence. ...
