On plank coverings of cube annuli

Gergely Ambrus, Matthew Corbo, Dakota Nobuyuki Goto +2

We study plank coverings of cube annuli $Q ∖ δ Q \subset R^{d}$ , where $Q$ is the $d$ -dimensional unit cube and $δ Q$ is a homothetic copy lying in its interior. A. Bezdek…

Connectivity and Diameter of Friends and Strangers Graphs Using Minimum Degree

Kai Mawhinney

Given graphs $X, Y$ on $n$ vertices, Defant and Kravitz defined the friends and strangers graph, denoted $FS (X, Y)$ . The vertices of $FS (X, Y)$ are bijections $σ:V(X…

Matroids with cycle systems are regular

Anton Dochtermann, Evan Huang, Kai Mawhinney +2

A cycle system for a matroid $M$ is a collection of cycles (unions of circuits) whose intersection properties mimic the cut sets of a graph. Cycle systems were introduced by Corry,…

A statistic-swapping involution on the Cartesian product of the symmetric group $S_{k n}$ and the generalized symmetric group $S (k, n)$

Peter Kagey, Kai Mawhinney

We construct a statistic-swapping involution on the Cartesian product of the generalized symmetric group $S (k, n)$ with the symmetric group $S_{k n}$ , which swaps the number of fixed…
