Intertwiners of representations of exceptional type quantum affine superalgebras
Keshav Dahiya, Evgeny Mukhin
We give explicit formulas for the smallest non-trivial irreducible representation of quantum affine superalgebras in types D, (in the all-fermionic…

Intertwiners of representations of twisted quantum affine algebras
Keshav Dahiya, Evgeny Mukhin
We use the -characters to compute explicit expressions of the -matrices for first fundamental representations of all types of twisted quantum affine algebras.
math.QA2025
Intertwiners of representations of untwisted quantum affine algebras and Yangians revisited
Keshav Dahiya, Evgeny Mukhin
We discuss applications of the -characters to the computation of the -matrices. In particular, we describe the -matrix acting in the tensor square of the first fundamental…
