Numerical Metrics, Curvature Expansions and Calabi-Yau Manifolds
Wei Cui, James Gray
We discuss the extent to which numerical techniques for computing approximations to Ricci-flat metrics can be used to investigate hierarchies of curvature scales on Calabi-Yau mani…

On the presentation of Hecke-Hopf algebras for non-simply-laced type
Weideng Cui
Hecke-Hopf algebras were defined by A. Berenstein and D. Kazhdan. We give an explicit presentation of an Hecke-Hopf algebra when the parameter associated to any two disti…
