Uniform description of the rigged configuration bijection

preprint2020arXivOpen access

Abstract

We give a uniform description of the bijection ΦΦ from rigged configurations to tensor products of Kirillov--Reshetikhin crystals of the form ⨂i=1NBri,1\bigotimes_{i=1}^N B^{r_i,1} in dual untwisted types: simply-laced types and types A2n−1(2)A_{2n-1}^{(2)}, Dn+1(2)D_{n+1}^{(2)}, E6(2)E_6^{(2)}, and D4(3)D_4^{(3)}. We give a uniform proof that ΦΦ is a bijection and preserves statistics. We describe ΦΦ uniformly using virtual crystals for all remaining types, but our proofs are type-specific. We also give a uniform proof that ΦΦ is a bijection for ⨂i=1NBri,si\bigotimes_{i=1}^N B^{r_i,s_i} when rir_i, for all ii, map to 00 under an automorphism of the Dynkin diagram. Furthermore, we give a description of the Kirillov--Reshetikhin crystals Br,1B^{r,1} using tableaux of a fixed height krk_r depending on rr in all affine types. Additionally, we are able to describe crystals Br,sB^{r,s} using kr×sk_r \times s shaped tableaux that are conjecturally the crystal basis for Kirillov--Reshetikhin modules for various nodes rr.
