COSPECTRALITY MEASURES OF GRAPHS WITH AT MOST SIX VERTICES
Cospectrality of two graphs measures the differences between the ordered spectrum of these graphs in various ways. Actually, the origin of this concept came back to Richard Brualdi's problems that are proposed in cite{braldi}: Let $G_n$ and $G'_n$ be two nonisomorphic simple graphs on $n$ vertices with spectra$$lambda_1 geq lambda_2 geq cdots geq lambda_n ;;;text{and};;; lambda'_1 geq lambda'_2...

15 صفحه اولSmith Invariants and Dual Graded Graphs
Abstract. The aim of this paper is to present evidence for a simple conjectural relation between eigenvalues and invariant factors of incidence matrices associated with adjacent ranks in differential posets. The conjectural relation yields the Smith invariants immediately, as the eigenvalues are completely understood [3, 15]. Furthermore, we consider more general structures: dual graded graphs ...
