A tensor formalism for multilayer network centrality measures using the Einstein product
Smahane El-Halouy, Silvia Noschese, Lothar Reichel
Complex systems that consist of different kinds of entities that interact in different ways can be modeled by multilayer networks. This paper uses the tensor formalism with the Ein…
The structured distance to singularity of a symmetric tridiagonal Toeplitz matrix
Silvia Noschese
This paper is concerned with the distance of a symmetric tridiagonal Toeplitz matrix to the variety of similarly structured singular matrices, and with determining the closest…
Perron communicability and sensitivity of multilayer networks
Smahane El-Halouy, Silvia Noschese, Lothar Reichel
Modeling complex systems that consist of different types of objects leads to multilayer networks, where nodes in the different layers represent different kind of objects. Nodes are…
On the banded Toeplitz structured distance to symmetric positive semidefiniteness
Silvia Noschese, Lothar Reichel
This paper is concerned with the determination of a close real banded positive definite Toeplitz matrix in the Frobenius norm to a given square real banded matrix. While it is stra…
