Jellyfish Partition Categories

  • Jonathan Comes


For each positive integer n, we introduce a monoidal category \(\mathcal {J}\mathcal {P}(n)\) using a generalization of partition diagrams. When the characteristic of the ground field is either 0 or at least n, we show \(\mathcal {J}\mathcal {P}(n)\) is monoidally equivalent to the full subcategory of Rep(An) whose objects are tensor powers of the natural n-dimensional permutation representation of the alternating group An.

I would like to thank Jonathan Kujawa for initiating this project by pointing out the paper [6], and for several useful conversations since. Part of this project was completed while I enjoyed a visit to the Max Planck Institute in Bonn. I would like to thank the institute for their hospitality.
