Jacobson’s conjecture and skew PBW extensions [PDF]

open access: yesRevista Integración, 2014
The aim of this paper is to compute the Jacobson’s radical of skew PBW extensions over domains. As a consequence of this result we obtain a direct relation between these extensions and the Jacobson’s conjecture, which implies that skew PBW extensions ...

Universal Enveloping Algebras of PBW Type [PDF]

open access: yesGlasgow Mathematical Journal, 2011
We continue our investigation of the general notion of universal enveloping algebra introduced in [A. Ardizzoni, "A Milnor-Moore Type Theorem for Primitively Generated Braided Bialgebras", J. Algebra 327 (2011), no. 1, 337--365].

Centralizers in PBW Extensions [PDF]

open access: yes, 2020
In this article we give a description for the centralizer of the coefficient ring R in the skew PBW extension. We give an explicit description in the quasi-commutative case and state a necessary condition in the general case.

The PBW theorem for affine Yangians [PDF]

open access: yesTransformation Groups, 2020
We prove that the Yangian associated to an untwisted symmetric affine Kac–Moody Lie algebra is isomorphic to the Drinfeld double of a shuffle algebra. The latter is constructed in [YZ14] as an algebraic formalism of cohomological Hall algebras.

PBW-deformations of N-Koszul algebras [PDF]

open access: yesJournal of Algebra, 2006
For a quotient algebra U of the tensor algebra we give explicit conditions on its relations for U being a PBW-deformation of an N-Koszul algebra A. We show that there is a one-to-one correspondence between such deformations and a class of A∞-structures ...

Nakayama Automorphism of Some Skew PBW Extensions [PDF]

open access: yesIngeniería y Ciencia, 2019
Let R be an Artin-Schelter regular algebra and A = σ(R)⟨x1,...,xn⟩ a graded quasi-commutative skew PBW extension over R. In this paper we describe the Nakayama automorphism of A using the Nakayama automor- phism of the ring of coefficients R.

Gelfand-kirillov dimension of skew pbw extensions [PDF]

open access: yes, 2013
Gelfand-Kirillov dimension of Poincaré-Birkhoff-Witt (PBW for short) extensions was established by Matczuk ([15], Theorem A). Since PBW extensions are a particular example of skew PBWextensions (also called σ-PBW extensions), the aim of this paper is to ...

PBW-deformations of graded rings [PDF]

open access: yesIsrael Journal of Mathematics, 2022
We prove in a very general framework several versions of the classical Poincaré-Birkhoff-Witt Theorem, which extend results from [BeGi, BrGa, CS, HvOZ, WW]. Applications and examples are discussed in the last part of the paper.

Young Tableaux, Multisegments, and PBW Bases [PDF]

open access: yes, 2015
The crystals for finite dimensional representations of sln+1 can be realized using Young tableaux. The infinity crystal on the other hand is naturally realized using multisegments, and there is a simple description of each embedding B(λ) ,→ B(∞) in terms
