摘要

我们构造了Webster张量积代数的一个g-增强，对一个泛sl2 Verma模和几个可积不可约模的张量积进行了分类。在可积模为二维的情况下，我们证明了blob代数通过内函子作用于这类dg增强代数的派生范畴。这个动作与sl2的直言动作交织在一起。由此，我们导出了blob代数的一个分类。

Tensor product categorifications, Verma modules and the blob 2-category

We construct a dg-enhancement of Webster's tensor product algebras that categorifies the tensor product of a universal sl2 Verma module and several integrable irreducible modules. We show that the blob algebra acts via endofunctors on derived categories of such dg-enhanced algebras in the case when the integrable modules are two-dimensional. This action intertwines with the categorical action of sl2. From the above we derive a categorification of the blob algebra.
