Affine Yangians as Limits of Quantum Toroidal Algebras

Luan Bezerra, Iryna Kashuba, Hongda Lin

We establish a degeneration isomorphism between quantum toroidal algebras and untwisted affine Yangians, valid for all untwisted affine Kac-Moody Lie algebras. Specifically, we pro…

Representations of Quantum Affine General Linear Superalgebras at Arbitrary 01-Sequences

Hongda Lin, Honglian Zhang

In this paper, we investigate finite-dimensional irreducible representations of the quantum affine general linear superalgebra $\mathrm{U}_q\big(\widehat{\mathfrak{gl}}_{m|n,\mathb…

Drinfeld super Yangian of the exceptional Lie superalgebra

Hongda Lin, Honglian Zhang

In this paper, we establish the first rigorous framework for the Drinfeld super Yangian associated with an exceptional Lie superalgebra, which lacks a classical Lie algebraic count…

RTT presentation of coideal subalgebra of quantized enveloping algebra of type CI

Yingwen Zhang, Hongda Lin, Honglian Zhang

The pair consisting of a quantum group and its corresponding coideal subalgebra, known as a quantum symmetric pair, was developed independently by M. Noumi and G. Letzter through d…
