Paraunitary matrices and group rings [PDF]

open access: yesInternational Journal of Group Theory, 2014
Design methods for paraunitary matrices from complete orthogonal sets of idempotents and related matrix structuresare presented. These include techniques for designing non-separable multidimensional paraunitary matrices.

The Tropical Matrix Groups with Symmetric Idempotents

open access: yesDiscrete Dynamics in Nature and Society, 2018
In this paper we study the semigroup Mn(T) of all n×n tropical matrices under multiplication. We give a description of the tropical matrix groups containing a diagonal block idempotent matrix in which the main diagonal blocks are real matrices and other ...

Isomorphism of generalized triangular matrix-rings and recovery of tiles

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
We prove an isomorphism theorem for generalized triangular matrix-rings, over rings having only the idempotents 0and 1, in particular, over indecomposable commutative rings or over local rings (not necessarily commutative).

Idempotent distributive semirings II

open access: yesSemigroup Forum, 1983
In [2] it is shown that every idempotent distributive semiring is the Plonka sum of a semilattice ordered system of idempotent distributive semirings which satisfy the generalized absorption law x+xyx+x=x. We shall show that an idempotent distributive semiring which satisfies the above absorption law must be a subdirect product of a distributive ...

Classical quotient rings of generalized matrix rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1995
An associative ring R with identity is a generalized matrix ring with idempotent set E if E is a finite set of orthogonal idempotents of R whose sum is 1.
