El presente trabajo constituye una revisión de la construcción del álgebra de vértices universal envolvente de un álgebra de Lie conforme. Comenzamos dando los resultados básicos relacionados con las álgebras conformes y ...

In this article the universal Poisson enveloping algebra for a binary-Lie algebra is constructed. Taking a basis B{double-struck} of a binary-Lie algebra B, we consider the symmetric algebra S(B) of polynomials in the ...

This qualitative bibliographical research aimed to analyze the Course Pedagogical Process (CPP) of six Federal Universities (FU) in the state of Rio Grande do Sul (RS), Brazil, focusing on the pre-service education of ...

The problem of classification of Jordan bit-nodules over (non-semisimple) finite dimensional Jordan algebras with respect to their representation type is considered. The notions of diagram of a Jordan algebra and of Jordan ...

Extending the relation between semi-Heyting algebras and semi-Nelson algebras to dually hemimorphic semi-Heyting algebras, we introduce and study the variety of dually hemimorphic semi-Nelson algebras and some of its ...

Let L and H be two Lie algebras and UL and UH be their respective universal enveloping algebras. The isomorphism problem for universal enveloping algebras of Lie algebras asks us to determine under what conditions the ...

Free algebras with an arbitrary number of free generators in varieties of BL-algebras generated by one BL-chain that is an ordinal sum of a finite MV-chain Ln and a generalized BL-chain B are described in terms of weak ...
