Modular representations of Lie algebras of reductive groups and Humphreys' conjecture

Alexander Premet, Lewis Topley

Let be connected reductive algebraic group defined over an algebraically closed field of characteristic and suppose that is a good prime for the root system of ,…

Restricted shifted Yangians and restricted finite -algebras

Simon M. Goodwin, Lewis Topley

We study the truncated shifted Yangian over an algebraically closed field of characteristic , which is known to be isomorphic to the finite -alg…

A proof of the first Kac-Weisfeiler conjecture in large characteristics

Benjamin Martin, David Stewart, Akaki Tikaradze +1

In 1971, Kac and Weisfeiler made two influential conjectures describing the dimensions of simple modules of a restricted Lie algebra . The first predicts the maximal…

On the semi-centre of a Poisson algebra

Cesar Lecoutre, Lewis Topley

If is a Lie algebra then the semi-centre of the Poisson algebra is the subalgebra generated by ad-eigenvectors. In this paper we ab…

Transfer results for Frobenius extensions

Stephane Launois, Lewis Topley

We study Frobenius extensions which are free-filtered by a totally ordered, finitely generated abelian group, and their free-graded counterparts. First we show that the Frobenius p…
