Erratum to "B2-crystals: Axioms, structure, models" [J. Combin. Theory, Ser. A, 116 (2009), 265--289]
Abstract
In this erratum we explain how to implement some axioms stated in our paper of 2009 so as to obtain a purely "local" characterization for finite B2-crystals, which was declared but not clarified at some moments there. Also we correct some inaccuracies in that paper.
