We define a faithful linear monoidal functor from the partition category, and hence from Deligne’s category $\mathrm{\underline{Re}p}(S_t)$, to the additive Karoubi envelope of the Heisenberg category. We show that the induced map on Grothendieck rings is injective and corresponds to the Kronecker coproduct on symmetric functions.

将Deligne的类别$ \ mathrm {\ underline {Re} p}(S_t)$嵌入到Heisenberg类别中(并附带Christopher Ryba的附录)

我们从分区类别(因此从Deligne的类别$ \ mathrm {\ underline {Re} p}(S_t)$)到Heisenberg类别的加性Karoubi包络定义了一个忠实的线性Monoidal函子。我们表明,在Grothendieck环上的诱导图是内射的,并且对应于对称函数上的Kronecker副产物。
