Let f: A → B be a ring homomorphism of not necessarily unital rings and I A an ideal which is mapped by f isomorphically to an ideal of B. The obstruction to excision in K-theory is the failure of the map between relative ...

En el presente trabajo estudiamos los ideales primos asociados de algunos anillos no conmutativos de tipo polinomial. En la literatura encontramos que estos ideales fueron caracterizados en un primer trabajo por Brewer y ...

In this work, we focus on three objectives: first, we investigate fusible property on skew PBW extensions, recognizing conditions that guarantee the property for this family of algebras. Later, we turn our attention to the ...

The theory of representations and characters was introduced by Frobenious and others around of 1896. Frobenios defined the characters as functions of a finite group G to C associated with the CG-modules, and new results ...

Let B be the ring of bounded operators in a complex, separable Hilbert space. For p > 0 consider the Schatten ideal Lp consisting of those operators whose sequence of singular values is p-summable; put S = S p Lp. Let G ...

Neste trabalho, descrevemos cíclicas de reticulados algébricos Zn-rotacionados de dimensão ímpar. Essas construções são obtidas através da imersão Rn, via homomorfismo canônico, de determinados Z-módulos livres de posto ...
