Dual reflection groups for three-dimensional Artin--Schelter regular algebras

Lucas Buzaglo, Daniel Rogalski

By definition, a dual reflection group is a finite group which grades an Artin--Schelter regular algebra such that the identity component is again regular. In this paper,…

Lie subalgebras of vector fields on curves

Lucas Buzaglo, Colin Ingalls

We study the subalgebra structure of Krichever-Novikov algebras, which are Lie algebras of vector fields on smooth affine curves. Our main result is that every infinite-dimensional…

Coactions of cocommutative Hopf algebras on skew polynomial rings

Lucas Buzaglo, Daniel Rogalski

We classify the cocommutative Hopf algebras which coact inner-faithfully on (one-parameter) skew polynomial rings $A_q(n) = \Bbbk \langle x_1,\dots,x_n \rangle/(x_j x_i - q x_i x_j…

On the boundary Carrollian conformal algebra

Lucas Buzaglo, Xiao He, Tuan Anh Pham +3

We initiate the mathematical study of the boundary Carrollian conformal algebra (BCCA), an infinite-dimensional Lie algebra recently discovered in the context of Carrollian physics…

Enveloping algebras of derivations of commutative and noncommutative algebras

Jason Bell, Lucas Buzaglo

Let be a field of characteristic zero. Motivated by the fundamental question of whether it is possible for the universal enveloping algebra of an infinite-dimensional Lie a…

Central extensions, derivations, and automorphisms of semi-direct sums of the Witt algebra with its intermediate series modules

Lucas Buzaglo, Girish S. Vishwa

Lie algebras formed via semi-direct sums of the Witt algebra and its modules have become increasingly prominent in both physics and mathematics i…

Maximal dimensional subalgebras of general Cartan type Lie algebras

Jason Bell, Lucas Buzaglo

Let be a field of characteristic zero and let be the general Cartan type Lie algebra. In this pap…

Derivations, extensions, and rigidity of subalgebras of the Witt algebra

Lucas Buzaglo

Let be an algebraically closed field of characteristic 0. We study some cohomological properties of Lie subalgebras of the Witt algebra $W = \operatorname{Der}(\Bbbk[t,t^{-…

Enveloping algebras of Krichever-Novikov algebras are not noetherian

Lucas Buzaglo

This work is part of the overarching question of whether it is possible for the universal enveloping algebra of an infinite-dimensional Lie algebra to be noetherian. The main resul…
