The Classification of 3+1d Symmetry Enriched Topological Order
Thibault D. Décoppet, Matthew Yu
We use a 2-categorical version of (de-)equivariantization to classify (3+1)d topological orders with a finite -symmetry. In particular, we argue that (3+1)d fermionic topologica…

Invariants of 4-Dimensional 2-Handlebodies from the Temperley-Lieb Category in Positive Characteristic
Thibault D. Décoppet, Benjamin Haïoun
We investigate invariants of 4-dimensional 2-handlebodies associated to the Temperley-Lieb category in characteristic and at a primitive fourth root of unity. These invariant…
