Isomorphism between the R-matrix and Drinfeld presentations of quantum affine superalgebra for type
Pengfa Xu, Hongda Lin, Honglian Zhang
In this paper, we establish an explicit isomorphism between Drinfeld and R-matrix presentations of the quantum affine superalgebra associated with the general linear Lie superalgeb…

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…
