Products Of EP Operators On Hilbert C*-Modules
In this paper, the special attention is given to the product of two modular operators, and when at least one of them is EP, some interesting results is made, so the equivalent conditions are presented that imply the product of operators is EP. Also, some conditions are provided, for which the reverse order law is hold. Furthermore, it is proved that $P(RPQ)$ is idempotent, if $RPQ$†</...
متن کاملOn the Infinite Products of Matrices
In different fields in space researches, Scientists are in need to deal with the product of matrices. In this paper, we develop conditions under which a product of matrices chosen from a possibly infinite set of matrices 0 i i P , j M P j J k i P 0 k k i converges. There exists a vector norm such that all matrices in M are no expansive with respect to this norm and also ...
متن کاملRow Products of Random Matrices
Let ∆1, . . . ,∆K be d × n matrices. We define the row product of these matrices as a d × n matrix, whose rows are entry-wise products of rows of ∆1, . . . ,∆K . This construction arises in certain computer science problems. We study the question, to which extent the spectral and geometric properties of the row product of independent random matrices resemble those properties for a d × n matrix ...
متن کاملProducts of Random Rectangular Matrices
We study the asymptotic behaviour of points under matrix cocyles generated by rectangular matrices. In particular we prove a random Perron-Frobenius and a Multiplicative Ergodic Theorem. We also provide an example where such products of random rectangular matrices arise in the theory of random walks in random environments and where the Multiplicative Ergodic Theorem can be used to investigate r...
متن کاملOn Graded Qr Decompositions of Products of Matrices
This paper is concerned with the singular values and vectors of a product Mm = A1A2 · · ·Am of matrices of order n. The chief difficulty with computing them directly from Mm is that with increasing m the ratio of the small to the large singular values of Mm may fall below the rounding unit, so that the former are computed inaccurately. The solution proposed here is to compute recursively the fa...
