The N-queens Problem on a symmetric Toeplitz matrix
Zsuzsanna Szaniszlo, Maggy Tomova, Cindy Wyels
We consider the problem of placing nonattacking queens on a symmetric Toeplitz matrix. As in the -queens Problem on a chessboard, two queens may attack each oth…
Radio numbers for generalized prism graphs
Paul Martinez, Juan Ortiz, Maggy Tomova +1
A radio labeling is an assignment such that every distinct pair of vertices satisfies the inequality $d(u,v)+|c(u)-c(v)|\geq \diam(G)+1$. The…
The Radio Number of
Marc Morris-Rivera, Maggy Tomova, Cindy Wyels +1
Radio labeling is a variation of Hale's channel assignment problem, in which one seeks to assign positive integers to the vertices of a graph subject to certain constraints inv…
Width is not additive
Ryan Blair, Maggy Tomova
We develop a construction suggested by Scharlemann and Thompson to obtain an infinite family of pairs of knots and so that $w(K_α # K'_α)=max{w(K_α), w(K'_α)}$. This i…
