Some Homological Properties of SkewPBWExtensions

Abstract: We prove that if R is a left Noetherian and left regular ring then the same is true for any bijective skew P BW extension A of R. From this we get Serre's Theorem for such extensions. We show that skew P BW extensions and its localizations include a wide variety of rings and algebras of interest for modern mathematical physics such as P BW extensions, well known classes of Ore algebras, operator algebras, diffusion algebras, quantum algebras, quadratic algebras in 3-variables, skew quantum polynomials, among m… Show more

“…This relationship shows that cyclic homology can be considered as a Lie analogue of algebraic K-theory and it is sometimes referred to as non-commutative differential geometry. With this in mind, in the first part of this section we recall the higher algebraic K-theory of skew PBW extensions following [13], while the second part treats with the cyclic homology of skew PBW extensions.…”

“…Let n ≥ 1 and q be a matrix (q i j ) n×n whit entries in a field K where q ii = 1 y q i j q ji = 1 for all 1 ≤ i, j ≤ n. Then quantum affine n-space O q (K n ) is defined to be K−algebra generated by x 1 , · · · , x n with the relations x j x i = q i j x i x j for all 1 ≤ i, j ≤ n. The K−algebra O q (K n ) is skew Calabi-Yau whit the Nakayama automorphism ν such that ν(x i ) = ( n j=1 q ji )x i (see [30], Proposition 4.1). This K−algebra is a skew PBW extension (see [29]). …”
