摘要
Benson and Krause in 2008 studied the tensor product on the derived category of the Koszul dual of a finite $p$-group $G$, using the classifying space of $G$. They showed that, under Koszul duality, this tensor product corresponds to the ordinary tensor product on the derived category of $G$, which confirmed a conjecture of Krause from 2004.
Motivated by this, we construct a tensor product on the derived category of right A-infinity modules over an A-infinity algebra $A$ under the additional assumption that $A$ is a brace B-infinity algebra. As an application, we recover the tensor product on the derived category of the Koszul dual of a $p$-group. This talk is based on a joint work with Gongxiang Liu and Mengdie Zhang
