Numerical Range and Quadratic Numerical Range for Damped Systems
We prove new enclosures for the spectrum of non-selfadjoint operator matrices associated with second order linear differential equations z̈(t) +Dż(t) +A0z(t) = 0 in a Hilbert space. Our main tool is the quadratic numerical range for which we establish the spectral inclusion property under weak assumptions on the operators involved; in particular, the damping operator only needs to be accretive a...
متن کاملOn EP elements in a C∗-algebra
We give several characterizations of EP elements in C∗-algebras. The motivation for the factorization results comes in part from a recent paper by Drivaliaris, Karanasios and Pappas on Hilbert space operators. MSC: 46L05, 47A05
متن کاملNumerical Computation of Spectral Elements in Max-plus Algebra
We describe the specialization to max-plus algebra of Howard’s policy improvement scheme, which yields an algorithm to compute the solutions of spectral problems in the max-plus semiring. Experimentally, the algorithm shows a remarkable (almost linear) average execution time. Résumé: Nous spécialisons à l’algèbre max-plus l’itération sur les politiques de Howard, qui fournit un algorithme pour ...
متن کاملElliptical Range Theorems for Generalized Numerical Ranges of Quadratic Operators
The classical numerical range of a quadratic operator is an elliptical disk. This result is extended to different kinds of generalized numerical ranges. In particular, it is shown that for a given quadratic operator, the rank-k numerical range, the essential numerical range, and the q-numerical range are elliptical disks; the c-numerical range is a sum of elliptical disks, and the Davis-Wieland...
متن کاملC∗-algebras and Numerical Linear Algebra
Given a self adjoint operator A on a Hilbert space, suppose that that one wishes to compute the spectrum of A numerically. In practice, these problems often arise in such a way that the matrix of A relative to a natural basis is “sparse”. For example, discretized second order differential operators can be represented by doubly infinite tridiagonal matrices. In these cases it is easy and natural...
متن کاملInvariant elements in the dual Steenrod algebra
In this paper, we investigate the invariant elements of the dual mod $p$ Steenrod subalgebra ${mathcal{A}_p}^*$ under the conjugation map $chi$ and give bounds on the dimensions of $(chi-1)({mathcal{A}_p}^*)_d$, where $({mathcal{A}_p}^*)_d$ is the dimension of ${mathcal{A}_p}^*$ in degree $d$.
