The Drinfeld center of an oligomorphic tensor category
Pavel Etingof, Andrew Snowden
Recently, Harman and the second author introduced a new construction of pre-Tannakian tensor categories based on oligomorphic groups. We develop tools for analyzing the Drinfeld ce…
Classification of simple commutative algebras in the Delannoy category
Pavel Etingof, Andrew Snowden
The Delannoy category is an interesting pre-Tannakian category associated to the oligomorphic group of automorphisms of the totally ordered set . By c…
Improved unirationality for GL-varieties
Arthur Bik, Jan Draisma, Rob Eggermont +1
A -variety is a typically infinite dimensional variety equipped with a suitable action of the infinite general linear group . In earlier work, we establis…
The singular locus of a GL-variety
Christopher Heng Chiu, Alessandro Danelon, Andrew Snowden
A -variety is a (typically) infinite dimensional variety equipped with an action of the infinite general linear group. In recent work of the first two authors with…
The second Delannoy category
Kevin Coulembier, Andrew Snowden
In recent work, Harman and Snowden constructed a symmetric tensor category associated to an oligomorphic group equipped with a measure. The oligomorphic group of order…
Representations of finite matrix monoids
Nate Harman, Andrew Snowden, Elad Zelingher
Let be the multiplicative monoid of matrices over a finite field. The monoid algebra has been studied for several decades…
