Per-Spectral Characterizations Of Some Bipartite Graphs
Discussiones Mathematicae Graph Theory, 2017 A graph is said to be characterized by its permanental spectrum if there is no other non-isomorphic graph with the same permanental spectrum. In this paper, we investigate when a complete bipartite graph Kp,p with some edges deleted is determined by its ...

Convertible Subspaces of Hessenberg-Type Matrices
Mathematics, 2017 We describe subspaces of generalized Hessenberg matrices where the determinant is convertible into the permanent by affixing ± signs. An explicit characterization of convertible Hessenberg-type matrices is presented. We conclude that convertible matrices
