Simplicity of tensor products of Kirillov--Reshetikhin modules: nonexceptional affine and G types

Se-jin Oh, Travis Scrimshaw

We show the denominator formulas for the normalized $R$-matrix involving two arbitrary Kirillov--Reshetikhin (KR) modules $W_{m,a}^{(k)}$ and $W_{p,b}^{(l)}$ in all nonexceptional…
