de Finetti Lattices and Magog Triangles
Andrew Beveridge, Ian Calaway, Kristin Heysse
The order ideal of the Boolean lattice consists of all subsets of size at most . Let denote the poset refinement of induced by the rules: $i…
Eigenvalues, Smith normal form and determinantal ideals
Aida Abiad, Carlos A. Alfaro, Kristin Heysse +1
Determinantal ideals of graphs generalize, among others, the spectrum and the Smith normal form (SNF) of integer matrices associated to graphs. In this work we investigate the rela…
A construction of distance cospectral graphs
Kristin Heysse
The distance matrix of a connected graph is the symmetric matrix with columns and rows indexed by the vertices and entries that are the pairwise distances between the corresponding…
A cospectral family of graphs for the normalized Laplacian found by toggling
Steve Butler, Kristin Heysse
We give a construction of a family of (weighted) graphs that are pairwise cospectral with respect to the normalized Laplacian matrix, or equivalently probability transition matrix.…
