Two fast algorithms for finding the solution of the lower Hessenberg quasi-Toeplitz linear system from Markov chain [PDF]
Scientific ReportsWe present two fast algorithms for finding the solution of the nonsingular lower Hessenberg quasi-Toeplitz linear system stem from Markov chain. And we confirm the complexity of these two algorithms is both O $$(n\log n)$$ based on the fact that a lower ...

A novel chaotic system with one absolute term: stability, ultimate boundedness, and image encryption [PDF]
HeliyonThis paper proposes a system with an absolute term, exhibiting chaos. The system's dynamics are examined by computation of bifurcation and Lyapunov exponents. This system has a countable finite coexisting nested attractors.

Source Enumeration via Toeplitz Matrix Completion [PDF]
ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020 This paper addresses the problem of source enumeration by an array of sensors in the presence of noise whose spatial covariance structure is a diagonal matrix with possibly different variances, referred to non-iid noise hereafter, when the sources are uncorrelated.

Generalized Crofoot transform and applications
Concrete Operators, 2023 Matrix-valued asymmetric truncated Toeplitz operators are compressions of multiplication operators acting between two model spaces. These are the generalization of matrix-valued truncated Toeplitz operators. In this article, we describe symbols of matrix-

Matrix-valued Berezin-Toeplitz quantization [PDF]
Journal of Mathematical Physics, 2007 We generalize some earlier results on a Berezin-Toeplitz type of quantization on Hilbert spaces built over certain matrix domains. In the present, wider setting, the theory could be applied to systems possessing several kinematic and internal degrees of freedom.

Hamiltonicity in Directed Toeplitz Graphs with s1=1 and s3=4
Computational and Mathematical Methods, 2023 A directed Toeplitz graph Tns1,⋯,sk;t1,⋯,tl with vertices 1, 2, ⋯, n is a directed graph whose adjacency matrix is a Toeplitz matrix. In this paper, we investigate the Hamiltonicity in directed Toeplitz graphs Tns1,⋯,sk;t1,⋯,tl with s1=1 and s3=4.
