Jordan-Hölder property for shifted quantum affine algebras
David Hernandez, Huafeng Zhang
We prove that finite length representations of shifted quantum affine algebras in category are stable by fusion product. This implies that in the topolo…

Theta series for quantum loop algebras and Yangians
Huafeng Zhang
We introduce and study a family of power series, which we call Theta series, whose coefficients are in the tensor square of a quantum loop algebra. They arise from a coproduct fact…
