ABSTRACT: An in-depth description of an apparently forgotten matrix operation, the reversal operator, is developed. The properties of such an operation are also given, resulting in a new vector-matrix ...

Abstract: Space–time-modulated electromagnetic structures have become a topic of significant research interest due to their frequency-converting, amplifying, and nonreciprocal properties. In ...

It’s warming the planet and driving biodiversity loss. This year will be key to negotiating a global treaty to curb its impact. By Manuela Andreoni Plastic is truly ubiquitous. It’s in our clothes, ...

We present in this paper a new method for solving polynomial eigenvalue problem. We give methods that decompose a skew-Hamiltonian matrix using Cholesky like-decomposition. We transform first the ...

We demonstrate a method to systematically obtain eigenvalues and eigenstates of a many-body Hamiltonian describing collective neutrino oscillations. The method is derived from the Richardson-Gaudin ...

The matrices M1 and M0 are 178x178 and are attached with this email. They are from a finite element discretization of a beam. While LAPACK’s dggev is able to compute the eigenvalues for my matrices ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...
