Young wall model for $A_2^{(2)}$-type adjoint crystals (1709.10232v2)
Published 29 Sep 2017 in math.RT
Abstract: We construct a Young wall model for higher level $A_2{(2)}$-type adjoint crystals. The Young walls and reduced Young walls are defined in connection with affin energy function. We prove that the affine crystal consisiting of reduced Young walls provides a realization of highest weight crystals $B(\lambda)$ and $B(\infty)$.
