定义仿射划分代数

Defining an Affine Partition Algebra

Samuel Creedon, Maud De Visscher

摘要:

我们通过生成元和关系定义了一个仿射划分代数,并证明了关于这个新代数类似于其他仿射图代数的一些基本结果。特别地,我们证明了它推广了对称群与分划代数之间的Schur-Weyl对偶.我们也把它与最近由J. Brundan和M.瓦格斯此外,我们还证明了这个仿射划分范畴是海森堡范畴的一个完全monoidal子范畴。

英文摘要:

We define an affine partition algebra by generators and relations and prove a variety of basic results regarding this new algebra analogous to those of other affine diagram algebras. In particular we show that it extends the Schur-Weyl duality between the symmetric group and the partition algebra. We also relate it to the affine partition category recently defined by J. Brundan and M. Vargas. Moreover, we show that this affine partition category is a full monoidal subcategory of the Heisenberg category.
