New characterizations of weak group matrices
نویسندگان
چکیده
In this paper, we prove that a complex square matrix is weak group if the m-th power of commutes with its inverse, where m an arbitrary positive integer. Firstly, some new characterizations matrices are investigated by means core-EP decomposition. Secondly, study equivalent conditions using commutator and rank equalities. Finally, relationships between {m, k}-core EP matrices, k-EP given.

متن کاملCombinatorial Characterizations of K-matrices
We present a number of combinatorial characterizations of Kmatrices. This extends a theorem of Fiedler and Pták on linearalgebraic characterizations of K-matrices to the setting of oriented matroids. Our proof is elementary and simplifies the original proof substantially by exploiting the duality of oriented matroids. As an application, we show that a simple principal pivot method applied to th...
متن کاملCharacterizations of optimal scalings of matrices
A scaling of a non-negative, square matrix A .. 0 is a matrix of the form DAD-I, where Dis a non~negatjve. non-singular, diagonal, square matrix. For a non.-negative, rectangular matrix B .. 0 we define a scaling to be a matrix CBEI where C and E are non-negative, non-singular, diagonal, square matrices of the corresponding dimension. (For square matrices the latter definition allows more scali...
متن کاملCharacterizations of Posets via Weak States
Weak states on posets are defined which are in some analogy to states on orthomodular posets used in axiomatic quantum mechanics. It is shown how certain properties of the set of weak states characterize certain properties of the underlying poset. Orthomodular posets serve as algebraic models for logics in axiomatic quantum mechanics. States on them are considered which reflect the properties o...
متن کاملCharacterizations of weak Cauchy sn - symmetric spaces
This paper proves that a space X is a weak Cauchy sn-symmetric space iff it is a sequentially-quotient, π-image of a metric space, which answers a question posed by Z. Li. 2000 Mathematics Subject Classification: 54C05, 54C10, 54E40.
