摘要
作者把对应于U_q(sl_n)的弱Hopf代数的结构按代数结构和余代数结构进行分类.对应于U_q(sl_n)的弱Hopf代数的代数结构可以分解为U_q(sl_n)和多项式代数的直和.而对应于U_q(sl_n)的弱Hopf代数的余代数结构可按其Ext箭图进行分类.最后讨论这些代数结构和余代数结构如何可搭配成弱Hopf代数.
Weak Hopf algebras corresponding to Uq(sln) constructed by different types of weak extensions have different structures, which are classified by their algebra structures and coalgebra structures. The algebra structures of weak Hopf algebras corresponding to Uq(sln) can be written as a direct sum of Uq(sln) and algebras of polynomials. The coalgebra structures of weak Hopf algebras corresponding to Uq(sln) are classified by their Ext quivers.
