Abstract

In 1976, King defined certain tableaux model, called King tableaux in this paper, counting weight multiplicities of irreducible representation of the symplectic group Sp(2m)Sp(2m) for a given dominant weight. Since Kashiwara defined crystals, it is an open problem to provide a crystal structure on King tableaux. In this paper, we present crystal structures on King tableaux and semistandard oscillating tableaux. The semistandard oscillating tableaux naturally appear as QQ-tableaux in the symplectic version of RSK algorithms. As an application, we discuss Littlewood-Richardson coefficients for Sp(2m)Sp(2m) in terms of semistandard oscillating tableaux.
