Abstract

In this talk we present some results about skew PBW extensions which were introduced by Lezama in [1].
These extensions and its localizations include a wide variety of rings and algebras of interest for modern
mathematical physics such as PBW extensions, well known classes of Ore algebras, operator algebras,
di usion algebras, quantum algebras, quadratic algebras in 3-variables, skew quantum polynomials,
among many others.
