Allowable Spectral Perturbations for ZME-Matrices**
A ZME-matrix is a matrix A all of whose positive integer powers are Z-matrices, and whose odd powers are irreducible. We find a combinatorial partial order on the spectral idempotents of a ZME-matrix A which determines the allowable spectral perturbations B for which B is again a ZME-matrix. We apply this result to show that under certain restrictions, the product of two ZME-matrices is a ZME-m...
متن کاملSpectral Radii of Fixed Frobenius Norm Perturbations of Nonnegative Matrices
Let A be an n × n nonnegative matrix. In this paper we consider the problems of maximizing the spectral radii of (i) A + X and (ii) A + D, where X is a real n × n matrix whose Frobenius norm is restricted to be 1 and where D is as X but is further constrained to be a diagonal matrix. For both problems the maximums occur at nonnegative X and D, and we use tools of nonnegative matrices, most nota...
متن کاملPerturbations of Hermitian Matrices and Applications to Spectral Symbols
It is often observed in practice that matrix sequences {An}n generated by discretization methods applied to linear differential equations, possess a Spectral Symbol, that is a measurable function describing the asymptotic distribution of the eigenvalues of An. Sequences composed by Hermitian matrices own real spectral symbols, that can be derived through the axioms of Generalized Locally Toepli...
متن کاملPerturbations of Jordan matrices
We consider perturbations of a large Jordan matrix, either random and small in norm or of small rank. In both cases we show that most of the eigenvalues of the perturbed matrix are very close to a circle with centre at the origin. In the case of random perturbations we obtain an estimate of the number of eigenvalues that are well inside the circle in a certain asymptotic regime. In the case of ...
متن کاملStable Perturbations of Nonsymmetric Matrices
A complex matrix is said to be stable if all its eigenvalues have negative real part. Let J be a Jordan block with zeros on the diagonal and ones on the superdiagonal, and consider analytic matrix perturbations of the form A() = J + B + O(2), where is real and positive. A necessary condition on B for the stability of A() on an interval (0; 0), and a suucient condition on B for the existence of ...
