, 1997 The decomposition of a matrix A into a product of two or three matrices can (depending on the characteristics of those matrices) be a very useful first step in computing such things as the rank, the determinant, or an (ordinary or generalized) inverse (of A) as well as a solution to a linear system having A as its coefficient matrix.

Elliptic quantum curves of class S k $$ {\mathcal{S}}_k $$
Journal of High Energy Physics, 2021 Quantum curves arise from Seiberg-Witten curves associated to 4d N $$ \mathcal{N} $$ = 2 gauge theories by promoting coordinates to non-commutative operators.

Eigenvectors of block circulant and alternating circulant matrices [PDF]
, 2005 The eigenvectors and eigenvalues of block circulant matrices had been found for real symmetric matrices with symmetric submatrices, and for block circulant matrices with circulant submatrices. The eigenvectors are now found for general block circulant

Asian Journal of Control, EarlyView.Abstract This article addresses the cooperative output consensus tracking problem for high‐order heterogeneous multi‐agent systems via a distributed proportional‐integral‐derivative (PID)‐like control strategy and proposes two novel control methodologies for the tuning of the control gains, which do not require any assumption and/or limitation on agent

Asian Journal of Control, EarlyView.Abstract Large swarms often adopt a hierarchical network structure that incorporates information aggregation. Although this approach offers significant advantages in terms of communication efficiency and computational complexity, it can also lead to degradation due to information constraints.

Sustainable Finance Disclosure Versus Performance: A Clustering Approach
Business Strategy and the Environment, EarlyView.ABSTRACT The Sustainable Finance Disclosure Regulation (SFDR) imposes on investment companies the publication of sustainability related profiles of the portfolio creation process. This obligation seeks to enhance the information provided to customers on financial products with regard to the Environmental, Social and Governance (ESG) criteria.

APPLICATION OF THE RANDOM MATRIX THEORY ON THE CROSS-CORRELATION OF STOCK PRICES [PDF]
International Journal of Mathematical Modelling & Computations, 2016 The analysis of cross-correlations is extensively applied for understanding of interconnections in stock markets. Variety of methods are used in order to search stock cross-correlations including the Random Matrix Theory (RMT), the Principal Component ...

An Example of Symmetry Exploitation for Energy-related Eigencomputations
, 2009 One of the most used approaches in simulating materials is the tight-binding approximation. When using this method in a material simulation, it is necessary to compute the eigenvalues and eigenvectors of the Hamiltonian describing the system. In general,
