A characterization of the Delannoy category by Adams operations
Andrew Snowden, Noah Snyder
In recent joint work with Harman, we studied a pre-Tannakian category called the Delannoy category, and showed that it had numerous special properties. One of these is that the Ada…
Universal properties of Delannoy categories
Kevin Coulembier, Nate Harman, Andrew Snowden
Recently, the second and third authors introduced a new symmetric tensor category associated to an oligomorphic group with a measure . When…
A remark on automorphisms of tensor spaces
Alessandro Danelon, Andrew Snowden
A tensor space is a vector space equipped with a finite collection of multi-linear forms. In recent years, a rich theory of infinite dimensional tensor spaces has emerged. In this…
Classical interpolation categories
Nate Harman, Andrew Snowden
We study tensor categories that interpolate the representation categories of finite classical groups. There are (at least) two ways to approach these categories: via ultraproducts…
Biquadratic spaces of length two
Alessandro Danelon, Andrew Snowden
A tensor space is a vector space equipped with a finite collection of multilinear forms. The length of a tensor space is its length as a representation of its symmetry group. Infin…
