Equivariant deformation theory for nilpotent slices in symplectic Lie algebras
Filippo Ambrosio, Lewis Topley
The Slodowy slice is a flat Poisson deformation of its nilpotent part, and it was demonstrated by Lehn-Namikawa-Sorger that there is an interesting infinite family of nilpotent orb…
On induced completely prime primitive ideals in enveloping algebras of classical Lie algebras
Simon M. Goodwin, Lewis Topley, Matthew Westaway
A distinguished family of completely prime primitive ideals in the universal enveloping algebra of a reductive Lie algebra over are those ideals const…
Modular Representations of Truncated current Lie algebras
Matthew Chaffe, Lewis Topley
In this paper we consider the structure and representation theory of truncated current algebras associated to the Lie algebra $\mathfra…
The centre of the modular affine vertex algebra
Tomoyuki Arakawa, Lewis Topley, Juan J. Villarreal
The Feigin--Frenkel theorem states that, over the complex numbers, the centre of the universal affine vertex algebra at the critical level is an infinite rank polynomial algebra. T…
Category for truncated current Lie algebras
Matthew Chaffe, Lewis Topley
In this paper we study an analogue of the Bernstein--Gelfand--Gelfand category for truncated current Lie algebras attached to a complex semisimple Li…
