dc.description.abstractRecently the study of the spectrum of weighted (di)graphs has attracted the interest of many researchers. Here we express the characteristic polynomial of any (square) matrix A in terms of the determinant of the Coates graph of the matrix B = xI - A. By doing so we are able to generalize the well-known Schwenk's formulas for simple graphs to weighted digraphs.en
