Double Yangians and lattice quantum vertex algebras

Fei Kong, Haisheng Li

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

Twisted quantum affine algebras and equivariant -coordinated modules for quantum vertex algebras

Naihuan Jing, Fei Kong, Haisheng Li +1

This paper is about establishing a natural connection of quantum affine algebras with quantum vertex algebras. Among the main results, we establish -adic versions of the sma…
