Categorification via blocks of modular representations for sl(n)
Vinoth Nandakumar, Gufang Zhao
Bernstein, Frenkel, and Khovanov have constructed a categorification of tensor products of the standard representation of , where they use singular blocks of categ…
Algebraic elliptic cohomology and flops II: -cobordism
Marc Levine, Yaping Yang, Gufang Zhao
In this paper, we study the algebraic cobordism spectrum in the motivic stable homotopy category of Voevodsky over an arbitrary perfect field . Using the motivic Adams spe…
Cohomological Hall algebras and affine quantum groups
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…
