Noncommutative geometry of homogenized quantum 𝔰𝔩 (2, ℂ)
We examine the relationship between certain noncommutative analogues of projective 3-
space, ℙ 3, and the quantized enveloping algebras U q (sl 2). The relationship is mediated …

[HTML][HTML] Cocycle twists of 4-dimensional Sklyanin algebras
A Davies - Journal of Algebra, 2016 - Elsevier
We study cocycle twists of a 4-dimensional Sklyanin algebra A and a factor ring B which is a
twisted homogeneous coordinate ring. Twisting such algebras by the Klein four-group G, we …

New Artin-Schelter regular and Calabi-Yau algebras via normal extensions
We introduce a new method to construct 4-dimensional Artin-Schelter regular algebras as
normal extensions of (not necessarily noetherian) 3-dimensional ones. The method …
