Category of all two-colored partitions

The category of all two-colored partitions is a category of two-colored partitions inducing the co-representation categories of the symmetric groups.

Definition

By the category of all two-colored partitions one denotes the category of two-colored partitions $\Pscr^{\circ\bullet}$ whose morphism class is the set of all two-colored partitions. It was introduced by Tarrago and Weber in [TaWe18], Theorem 8.3 under the name $\mathcal{S}_{\mathrm{grp},\mathrm{glob}}(1)$.

A canonical generator of $\Pscr^{\circ\bullet}$ is the set $\{\Partition{\Pline (1,0) (2,1) \Pline (2,0) (1,1) \Ppoint 0 \Pw:1,2 \Ppoint 1 \Pw:1,2}, \raisebox{0.125em}{\LPartition{\Pw:1;\Pw:2}{0.6:1,2}}, \raisebox{0.125em}{\LPartition{\Pw:1,3;\Pb:2,4}{0.6:1,2,3,4}}, \LPartition{\Ls:1;\Pw:1}{}\}$.

Associated unitary easy quantum groups

The category of two-colored pair partitions with neutral blocks induces the co-representation categories of the symmetric groups $(S_N)_{N\in \N}$.
