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…
On deformed double current algebras for simple Lie algebras
Nicolas Guay, Yaping Yang
We prove the equivalence of two presentations of deformed double current algebras associated to a complex simple Lie algebra, the first one obtained via a degeneration of affine Ya…
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…
