초록

We construct a weak Hopf algebra $\wx$ corresponding to non-standard quantum group $X_q(A_1)$. The PBW basis of $\wx$ is described and all the highest weight modules of $\wx$ are classified. Finally we give the Clebsch-Gordan decomposition of the tensor product of two highest weight modules of $\wx$.

Abstract

We construct a weak Hopf algebra $\wx$ corresponding to non-standard quantum group $X_q(A_1)$. The PBW basis of $\wx$ is described and all the highest weight modules of $\wx$ are classified. Finally we give the Clebsch-Gordan decomposition of the tensor product of two highest weight modules of $\wx$.
