将H-Hopf代数结构引入到U q,p (Sl 2)中,研究了椭圆量子群U q,p (Sl 2)的顶点算子,其定义为无穷维U q,p (Sl 2)模的缠结算子。我们证明了顶点算子与先前使用拟hopf代数L3q,x (S[2])间接得到的结果一致。这表明即使在中心元非零的情况下,我们的H-Hopf代数体结构也具有一致性。
Introducing an H-Hopf algebroid structure into U q,p (Sl 2 ), we investigate the vertex operators of the elliptic quantum group U q,p (Sl 2 ) defined as intertwining operators of infinite dimensional U q,p (Sl 2 ) modules. We show that the vertex operators coincide with the previous results obtained indirectly by using the quasi-Hopf algebra L3q ,x (S[ 2 ). This shows a consistency of our H-Hopf algebroid structure even in the case with a nonzero central element.
