Double Yangians and quantum vertex algebras, I

Fei Kong, Haisheng Li

For any symmetrizable generalized Cartan matrix $A$ , we introduce an algebra $DY (A)$ , which is essentially the centrally extended double Yangian when $A$ is of…

Double Yangians and lattice quantum vertex algebras

Fei Kong, Haisheng Li

For any simply-laced GCM $A$ , a $C [[ℏ]]$ -algebra $DY (A)$ was introduced in [KL1], where it was proved that the universal vacuum $\widehat{\mathcal{D…
