A Difference Formula for Tensor-power Multiplicities
Hongfei Shu, Peng Zhao, Rui-Dong Zhu +1
A novel combinatorial formula is developed for for tensor product multiplicities in representation theory. We introduce a difference formula linking these multiplicities to restric…

Counting Bethe States in Twisted Spin Chains
Hongfei Shu, Peng Zhao, Rui-Dong Zhu +1
We present a counting formula that relates the number of physical Bethe states of integrable models with a twisted boundary condition to the number of states in the untwisted or pa…
