objective: citizenship identity as it is understood from the component words is a kind of distinction and recognition of intimates from outsiders which has a historical background. meaning of citizenship holds the concepts such as rights, responsibilities and duties, as well as a sense of belonging that in accordance with others and executive agencies will be meaningful and indicates a kind of ...

Symmetry for Comodule Categories

For coalgebras C over a field, we study when the categories CM of left C-comodules and MC of right C-comodules are symmetric categories, in the sense that there is a duality between the categories of finitely presented unitary left R-modules and finitely presented unitary left L-modules, where R and L are the functor rings associated to the finitely accessible categories CM and MC .

Module and Comodule Categories - a Survey

The theory of modules over associative algebras and the theory of comodules for coassociative coalgebras were developed fairly independently during the last decades. In this survey we display an intimate connection between these areas by the notion of categories subgenerated by an object. After a review of the relevant techniques in categories of left modules, applications to the bimodule struc...

On Certain Identity Related to Jordan

In this paper we prove the following result. LetH be a real or complex Hilbert space, let L(H) be the algebra of all bounded linear operators on H and let A(H) ⊆ L(H) be a standard operator algebra. Suppose we have an additive mapping D : A(H) → L(H) satisfying the relation D(An) = D(A)A∗n−1 + AD(An−2)A∗ + An−1D(A) for all A ∈ A(H) and some fixed integer n > 1. In this case there exists a uniqu...
