On the description of the Leibniz algebras with nilindex n-3
description of the Leibniz algebras nilindex n-3
2011/1/20
In this paper we present the classification of a subclass of natu-rally graded Leibniz algebras. These n-dimensional Leibniz algebras have the characteristic sequence equal to (n−3, 3). For this...
Classifying $C^*$-algebras with both finite and infinite subquotients
Classification Extensions Graph algebras
2010/12/13
We give a classification result for a certain class of C∗-algebras A over a finite topological space X in which there exists an open set U of X such that U separates the finite and infinite subq...
On quasitriangular structures in Hopf algebras arising from exact group factorizations
quasitriangular structures Hopf algebras exact group factorizations
2010/12/10
We show that bicrossed product Hopf algebras arising from exact factorizations in almost simple finite groups, so in particular, in simple and symmetric groups, admit no uasitriangular structure.
Some remarks on big Cohen-Macaulay algebras via closure operations
Almost Cohen-Macaulay Big Cohen-Macaulay Closure operation Perfect al-gebra Value map
2010/12/1
In this note we present some remarks on big Cohen-Macaulay algebras.Our methods for doing this are inspired by the notion of dagger closure and by ideas of Northcott on dropping of the Noetherian assu...
Contractions of Filippov algebras
2010/11/29
We introduce in this paper the contractions Gc of n-Lie (or Filippov) algebras G and show that they have a semidirect structure as their n = 2 Lie algebra counterparts.As an example, we compute the no...
