Double Yangian, Factorization, and qKZ-equation for Cotangent Lie Algebras

Raschid Abedin, Wenjun Niu

In this paper, we construct the dual $Y_{ℏ}^{*} (d)$ and double $D Y_{ℏ} (d)$ of the Yangian $Y_{ℏ} (d)$ associated with a cotangent Lie algebra $\m…

Quantum groupoids from moduli spaces of $G$ -bundles

Raschid Abedin, Wenjun Niu

In a previous work, we have constructed the Yangian $Y_{ℏ} (d)$ of the cotangent Lie algebra $d = T^{*} g$ for a simple Lie algebra $g$ , fr…

Yangian for cotangent Lie algebras and spectral $R$ -matrices

Raschid Abedin, Wenjun Niu

In this paper, we present a canonical quantization of Lie bialgebra structures on the formal power series $d [[t]]$ with coefficients in the cotangent Lie algebra $\m…
