dc.description.abstract | M. Fiedler proved in [1] that the set of real n-by-n symmetric matrices A such that rank(A + D) ≥ n - 1 for every real diagonal matrix D is the set of matrices PT PT where P is a permutation matrix and T an irreducible tridiagonal matrix. We show that this result remains valid for arbitrary fields with some exceptions for 5-by-5 matrices over Z3 | en_US |
