Young wall model for <italic>A</italic>2(2)-type adjoint crystals.

We construct a Young wall model for higher level <inline-graphic></inline-graphic>-type adjoint crystals. The Young walls and reduced Young walls are defined in connection with affine energy function. We prove that the affine crystal consisting of reduced Young walls provides a realization of highest weight crystals <italic>B</italic>(λ) and <italic>B</italic>(∞). [ABSTRACT FROM AUTHOR]
