Min(Max) – Min(Max) – Max(Min) (∗): Compositions of Neutrosophic Fuzzy Matrices and its Application in Medical Diagnosis [PDF]
Neutrosophic Sets and SystemsIn this article, we introduce two types of compositions in Neutrosophic Fuzzy Matrices (NFM): max(min) - max(min) - min(max) (◦) and min(max) – min(max) – max(min) ( ∗) compositions.

Idempotents which are products of two nilpotents
Special MatricesOver any GCD (greatest common divisor) commutative domain we show that the nontrivial 2×22\times 2 idempotent matrices are products of two nilpotent matrices. In order to find explicitly such decompositions, two procedures are described.

A family of 512 reverse order laws for generalized inverses of a matrix product: A review
Heliyon, 2020 Reverse order laws for generalized inverses of matrix products are a classic object of study in the theory of generalized inverses. One of the well-known reverse order laws for a matrix product AB is (AB)(i,…,j)=B(s2,…,t2)A(s1,…,t1), where (⋅)(i,…,j ...

Isomorphic Operators and Functional Equations for the Skew-Circulant Algebra
Abstract and Applied Analysis, 2014 The skew-circulant matrix has been used in solving ordinary differential equations. We prove that the set of skew-circulants with complex entries has an idempotent basis. On that basis, a skew-cyclic group of automorphisms and functional equations on the

Solution Set of the Yang-Baxter-like Matrix Equation for an Idempotent Matrix
Symmetry, 2022 Given a complex idempotent matrix A, we derive simple, sufficient and necessary conditions for a matrix X being a nontrivial solution of the Yang-Baxter-like matrix equation AXA = XAX, discriminating commuting solutions from non-commuting ones. On this basis, we construct all the commuting solutions of the nonlinear matrix equation.
