Exploiting the Kronecker product structure of φ−functions in exponential integrators
International Journal for Numerical Methods in Engineering, 2022 Exponential time integrators are well‐established discretization methods for time semilinear systems of ordinary differential equations. These methods use φ− functions, which are matrix functions related to the exponential.

Generalization of MacNeish’s Kronecker product theorem of mutually orthogonal Latin squares
AKCE International Journal of Graphs and Combinatorics, 2021 The subject of mutually orthogonal Latin squares (MOLSs) has fascinated researchers for many years. Although there is a number of intriguing results in this area, many open problems remain to which the answers seem as elusive as ever. Mutually orthogonal

Notes and counterexamples on positive (semi) definite properties of some matrix products
Ain Shams Engineering Journal, 2018 In the present paper, we give some notes and counterexamples to show that the positive (semi) definite property of the Khatri-Rao and Tracy-Singh products of partitioned matrices are in general incorrect and show also that the matrix triangle inequality ...

Exponent-critical primitive graphs and the Kronecker product
Electronic Journal of Graph Theory and Applications, 2019 A directed graph is primitive of exponent t if it contains walks of length t between all pairs of vertices, and t is minimal with this property. Moreover, it is exponent-critical if the deletion of any arc results in an imprimitive graph or in a ...

Joint Data Compression and Parameter Estimation for Kronecker Product Structure
IEEE Access, 2019 Due to the existence of high-dimensional data originating from observation matrices with the Kronecker product structure, it is possible to achieve cost-effective data processing by utilizing such a structure. This paper proposes an open issue, i.e., the
