Some Properties of the Characteristic Polynomial
of a Nonnegative Matrix
Institute of Information Technologies, 1113 Sofia
In this paper, we extend and generalize some of the well known spectral properties of a nonnegative matrix by establishing analogous properties for the zeros of derivatives of the characteristic polynomial of such a matrix.
Keywords: nonnegative matrix,Perron-Frobenius theory, characteristic polynomial.
