Continuous-Time Linear Periodic Systems: A Note on the Controllability Interval Length
Autor: Vasilii Zaitsev
Publikováno v: IEEE Transactions on Automatic Control. 67:520-525
Continuous-time linear systems with periodic coefficients of period T are considered in this paper. We study the question of the controllability interval length of periodic systems. It is known that a controllable T-periodic system is controllable ov

Preconditioned iterative method for nonsymmetric saddle point linear systems
Autor: Li-Dan Liao, Xiang Wang, Guo-Feng Zhang
Publikováno v: Computers & Mathematics with Applications. 98:69-80
In this paper, a new preconditioned iterative method is presented to solve a class of nonsymmetric nonsingular or singular saddle point problems. The implementation of the proposed preconditioned Krylov subspace method avoids solving inverse of Schur

On real algebraic numbers in which the derivative of their minimal polynomial is small
Autor: D. V. Koleda
Publikováno v: Proceedings of the National Academy of Sciences of Belarus. Physics and Mathematics Series. 57:135-147
Algebraic numbers are the roots of integer polynomials. Each algebraic number α is characterized by its minimal polynomial Pα that is a polynomial of minimal positive degree with integer coprime coefficients, α being its root. The degree of α is

Minimum-Degree Distributed Graph Filter Design
Autor: Lihua Xie, Kemi Ding, Junfeng Wu
Publikováno v: IEEE Transactions on Signal Processing. 69:1083-1096
Here we consider the problem of designing finite-impulse-response (FIR) graph filter (GF) in a fully distributed way. For a directed graph with $\mathsf {N}$ nodes, each node designs filter coefficients in a distributed manner, when the knowledge of

Rational Criteria for Diagonalizability of Real Matrices
Autor: João Ferreira Alves
Publikováno v: The Electronic Journal of Linear Algebra. 36:664-677
The purpose of this note is to obtain rational criteria for diagonalizability of real matrices through the analysis of the moment and Gram matrices associated to a given real matrix. These concepts were introduced by Horn and Lopatin in [R.A. Horn an

A new preconditioner for a class of $$2\times 2$$ block linear systems
Autor: Shu-Xin Miao
Publikováno v: Japan Journal of Industrial and Applied Mathematics. 37:913-928
In this paper, a new preconditioner for a class of $$2\times 2$$ block linear systems is proposed. The proposed new preconditioner is a better approximation to the original coefficient matrix than the previous ones. The eigenvalue distribution and an

Publikováno v: Mathematics
Volume 9
Issue 18
Mathematics, Vol 9, Iss 2285, p 2285 (2021)
Linear complexity is an important property to measure the unpredictability of pseudo-random sequences. Trace representation is helpful for analyzing cryptography properties of pseudo-random sequences. In this paper, a class of new Ding generalized cy

On the Similarity of Certain Integer Matrices with Single Eigenvalue over the Ring of Integers
Autor: S. V. Sidorov
Publikováno v: Mathematical Notes. 105:756-762
The problem of the similarity of integer matrices with single eigenvalue over the ring of integers is considered. A criterion for a matrix to be similar to a Jordan block is obtained. In addition, a similarity criterion for matrices whose minimal pol

Linear groups of degree 3 over a field that contain a one-parametric group of elements with minimal polynomial (x−1)3
Autor: C. Kanta Gupta, Evgenii L. Bashkirov
