R-matrices for quantum affine algebras and Khovanov-Lauda-Rouquier algebras, I

Seok-Jin Kang, Masaki Kashiwara, Myungho Kim

Let us consider a finite set of pairs consisting of good $U_q^{\prime }(g)$-modules and invertible elements. The distribution of poles of normalized R-matrices yields Khovanov-Lauda-Rouquie…
