Frobenius Heisenberg分类

Frobenius Heisenberg categorification

Alistair Savage

摘要:

我们将分次Monoidal超范畴$\mathcal{H}\mathit{eis}_{F,k}$关联到每个分次Frobenius超代数$F$和整数$k$ .这些类别,其中分类广泛的格海森堡代数,恢复许多以前定义的海森堡类别的特殊情况。以这种方式,范畴$\mathcal{H}\mathit{eis}_{F,k}$作为海森堡分类的统一和推广框架。即使在以前定义的海森堡类别的情况下,我们获得新的,更有效的,介绍这些类别的基础上,布伦丹的方法。当$k=0$,我们的建设产生新的版本的仿射导向Brauer范畴取决于一个分次Frobenius超代数。

英文摘要:

We associate a graded monoidal supercategory $\mathcal{H}\mathit{eis}_{F,k}$ to every graded Frobenius superalgebra $F$ and integer $k$. These categories, which categorify a broad range of lattice Heisenberg algebras, recover many previously defined Heisenberg categories as special cases. In this way, the categories $\mathcal{H}\mathit{eis}_{F,k}$ serve as a unifying and generalizing framework for Heisenberg categorification. Even in the case of previously defined Heisenberg categories, we obtain new, more efficient, presentations of these categories, based on an approach of Brundan. When $k=0$, our construction yields new versions of the affine oriented Brauer category depending on a graded Frobenius superalgebra.
