Arboreal tensor categories
Nate Harman, Ilia Nekrasov, Andrew Snowden
We introduce some new symmetric tensor categories based on the combinatorics of trees: a discrete family , for an integer, and a continuous family $\mathc…
Discrete pre-Tannakian categories
Nate Harman, Andrew Snowden
Pre-Tannakian categories are a natural class of tensor categories that can be viewed as generalizations of algebraic groups. We define a pre-Tannkian category to be discrete if it…
The circular Delannoy category
Nate Harman, Andrew Snowden, Noah Snyder
Let (resp. ) be the group of orientation preserving self-homeomorphisms of the unit circle (resp. real line). In previous work, the first two authors constructed pre-Tannaki…
Pre-Galois categories and Fraïssé's theorem
Nate Harman, Andrew Snowden
Galois categories can be viewed as the combinatorial analog of Tannakian categories. We introduce the notion of pre-Galois category, which can be viewed as the combinatorial analog…
