The Smith normal form distribution of a random integer matrix [PDF]
Discrete Mathematics & Theoretical Computer Science, 2020 We show that the density μ of the Smith normal form (SNF) of a random integer matrix exists and equals a product of densities μps of SNF over Z/psZ with p a prime and s some positive integer.

Normal matrix compressions [PDF]
Operators and Matrices, 2013 The recently developed theory of higher--rank numerical ranges originated in problems of error correction in quantum information theory but its mathematical implications now include a quite satisfactory understanding of \emph{scalar} compressions of complex matrices. Here our aim is to make some first steps in the more general program of understanding \

THE VARIATION OF THE SPECTRUM OF A NORMAL MATRIX
Duke Mathematical Journal, 1953 In dieser Note wird der folgende Satz bewiesen: Es seien \( A, B \) normale Matrizen mit den Eigenwerten \( \alpha_{1}, \ldots, \alpha_{n} \) und \( \beta_{1}, \ldots, \beta_{n} \). Man kann die Eigenwerte so anordnen, da \( B \Sigma\left|\alpha_{\imath}-\beta_{i}\right|^{2} \leq\|A-B\|^{2} \) ist.

Finding the closest normal structured matrix
Linear Algebra and its Applications, 2021 Given a structured matrix $A$ we study the problem of finding the closest normal matrix with the same structure. The structures of our interest are: Hamiltonian, skew-Hamiltonian, per-Hermitian, and perskew-Hermitian. We develop a structure-preserving Jacobi-type algorithm for finding the closest normal structured matrix and show that such algorithm ...

Matrix Metalloproteinases of Normal Human Tissues
Biochemistry (Moscow), 2001 This review considers biochemical properties of the family of matrix metalloproteinases (MMPs) of normal human tissues and the involvement of these enzymes in morphogenesis. Four main MMP subfamilies are characterized, and a group of other MMPs is described.

A Bayesian Procedure to Identify the Orders of Vector Moving Average Processes with Seasonality [PDF]
The Egyptian Statistical Journal, 2020 This article develops an approximate Bayesian procedure to identify the orders of vector moving average processes with seasonality. The proposed is based on approximating the likelihood function by a matrix normal – Wishart on the parameter space ...

Matrix normalization for optimal robot design [PDF]
Proceedings. 1998 IEEE International Conference on Robotics and Automation (Cat. No.98CH36146), 2002 Good robot performance often relies upon the selection of design parameters that lead to a well conditioned Jacobian or impedance "design" matrix. In this paper a new design matrix normalization technique is presented to cope with the problem of nonhomogeneous physical units.

Quasi-normal modes from non-commutative matrix dynamics
Journal of High Energy Physics, 2017 We explore similarities between the process of relaxation in the BMN matrix model and the physics of black holes in AdS/CFT. Focusing on Dyson-fluid solutions of the matrix model, we perform numerical simulations of the real time dynamics of the system ...
