Semisimplicity criterion for 2-tonal partition algebras

Representation Theory 2026-04-06 v1

Abstract

We determine the semisimplicity criterion for even partition algebras over the complex field. Specifically we prove that the even/2-tonal partition algebras Pn2(δ)P_n^2(\delta) over C\mathbb{C} are semisimple for all nn if and only if parameter δ∉N0\delta \not\in \mathbb{N}_0 .
