Yaping Yang, Gufang Zhao
We study the preprojective cohomological Hall algebra (CoHA) introduced by the authors in an earlier work for any quiver and any one-parameter formal group . In thi…

On two cohomological Hall algebras
Yaping Yang, Gufang Zhao
We compare two cohomological Hall algebras (CoHA). The first one is the preprojective CoHA introduced by the authors in arXiv:1407.7994 associated to each quiver Q, and each algebr…
