Maulik-Okounkov quantum loop groups and Drinfeld double of preprojective $K$ -theoretic Hall algebras

Tianqing Zhu

In this paper we prove the following results: Given the Drinfeld double $A_{Q}^{e x t}$ of the localised preprojective $K$ -theoretic Hall algebra $A_{Q}^{+}$ of q…

From quantum difference equation to Dubrovin connection of affine type A quiver varieties

Tianqing Zhu

This is the continuation of the article \cite{Z23}. In this article we will give a detailed analysis of the quantum difference equation of the equivariant $K$ -theory of the affine…
