Combinatorial aspects of normal ordering of 3-dimensional skew polynomial rings

Andrés Rubiano, Armando Reyes

In this paper, we discuss combinatorial aspects of normal ordering of 3-dimensional skew polynomial rings defined and classified by Bell and Smith \cite{BellSmith1990}. With some h…

Noncommutative differential geometry of ambiskew polynomial rings

Andrés Rubiano, Armando Reyes

We determine sufficient criteria for the differential smoothness of ambiskew polynomial rings defined and studied by D. A. Jordan in several papers \cite{FishJordan2019, Jordan1993…

On the smoothness of 3-dimensional skew polynomial rings

Andrés Rubiano, Armando Reyes

This paper is part of a series of papers in which we have investigated the differential smoothness of families of noncommutative algebras. Here, we consider this topic for the fami…

Smooth geometry of skew PBW extensions over commutative polynomial rings I

Andrés Rubiano, Armando Reyes

In this paper, we investigate the differential smoothness of skew PBW extensions over commutative polynomial rings on one and two indeterminates.
