Crystal Structure on Rigged Configurations and the Filling Map

In this paper, we extend work of the first author on a crystal structure on rigged configurations of simply-laced type to all non-exceptional affine types using the technology of virtual rigged configurations and crystals. Under the bijection between rigged configurations and tensor products of Kirillov–Reshetikhin crystals specialized to a single tensor factor, we obtain a new tableaux model for Kirillov– Reshetikhin crystals. This is related to the model in terms of Kashiwara–Nakashima tableaux via a filling map, generalizing the recently discovered filling map in type D (1) n .
