The Tropical Matrix Groups with Symmetric Idempotents
Discrete 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
International 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).

Paraunitary matrices and group rings [PDF]
International 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.

On algebras generated by idempotents
, 2017 Idempotents ($e^2=e$) in (nonassociative commutative) algebras (e.g., Jordan algebras) behave sometimes like involutions in a group. Indeed, in some (very) interesting cases one can associate an involutive automorphism of the algebra to an idempotent ...

Idempotents for derangement numbers
Discrete Mathematics, 2003 The principal result of this paper locates a set of orthogonal idempotents in Solomon's descent algebra. The representations of the symmetric group arising from these idempotents have dimensions which are equal to the number of permutations with a particular number of fixed points.
