Neutrosophic Fuzzy Matrices and Some Algebraic Operations [PDF]
Neutrosophic Sets and Systems, 2020 In this article, we study neutrosophic fuzzy set and define the subtraction and multiplication of two rectangular and square neutrosophic fuzzy matrices.

Generalised Homotopy and Commutativity Principle [PDF]
Journal of Pure and Applied Algebra, 2022 A BSTRACT . In this paper, we study the action of special n × n linear (resp. symplectic) matrices which are homotopic to identity on the right invertible n × m matrices.

COMMUTATORS OF SKEW-SYMMETRIC MATRICES [PDF]
International Journal of Bifurcation and Chaos, 2005 In this paper we develop a theory for analysing the "radius" of the Lie algebra of a matrix Lie group, which is a measure of the size of its commutators. Complete details are given for the Lie algebra 𝔰𝔬(n) of skew symmetric matrices where we prove [Formula: see text], X, Y ∈ 𝔰𝔬(n), for the Frobenius norm. We indicate how these ideas might be extended

Local discrimination of generalized Bell states via commutativity [PDF]
Physical Review A, 2021 We studied the distinguishability of generalized Bell states under local operations and classical communication. We introduced the concept of maximally commutative set (MCS), subset of generalized Pauli matrices whose elements are mutually commutative ...

An Ising-type formulation of the six-vertex model
Nuclear Physics B, 2023 We show that the celebrated six-vertex model of statistical mechanics (along with its multistate generalizations) can be reformulated as an Ising-type model with only a two-spin interaction.

Generalizations of some classical theorems to D-normal operators on Hilbert spaces
Journal of Inequalities and Applications, 2020 We say that a Drazin invertible operator T on Hilbert space is of class [ D N ] $[DN]$ if T D T ∗ = T ∗ T D $T^{D}T^{*} = T^{*}T^{D}$ . The authors in (Oper. Matrices 12(2):465–487, 2018) studied several properties of this class.
