作为弱Hopf代数与缠绕结构的推广,本文引进弱Hopf π-代数与弱群缠绕结构,并证明两者之间有着密切的关系:设H={Hα}α∈π是一族余......

In this paper we mainly reveal the rich cohomology theories for partial entwining structures....

In this paper the integrals of entwining structure (A,C,ψ) are discussed, where A is a k-algebra, C a k-coalgebra and a......
