Integer invariants of abelian Cayley graphs

Joshua E. Ducey, Deelan M. Jalil

Let $G$ be a finite abelian group, let $E$ be a subset of $G$ , and form the Cayley (directed) graph of $G$ with connecting set $E$ . We explain how, for various matrices associated…

Integer invariants of an incidence matrix related to Rota's basis conjecture

Stephanie Bittner, Joshua Ducey, Xuyi Guo +2

We compute the spectrum and Smith normal form of the incidence matrix of disjoint transversals, a combinatorial object closely related to the n-dimensional case of Rota's basis con…
