Inertias of Laplacian matrices of weighted signed graphs
Keivan Hassani Monfared, Gary MacGillivray, Dale D. Olesky +1
We study the sets of inertias achieved by Laplacian matrices of weighted signed graphs. First we characterize signed graphs with a unique Laplacian inertia. Then we show that there…
The sepr-sets of sign patterns
Leslie Hogben, Jephian C. -H. Lin, D. D. Olesky +1
Given a real symmetric matrix, the sepr-sequence records information about the existence of principal minors of each order that are positive, negative,…
Bordering for spectrally arbitrary sign patterns
Dale Olesky, Pauline van den Driessche, Kevin N. Vander Meulen
We develop a matrix bordering technique that can be applied to an irreducible spectrally arbitrary sign pattern to construct a higher order spectrally arbitrary sign pattern. This…
