- In the second part of this thesis we prove that if the Hopf Galois extension is cocentral, and the invariants is a Hopf algebra then $A$ is itself a Hopf algebra. 设%24H%24是域%24k%24上的余半单Hopf代数，%24A%24为双代数且%24H%24在%24A%24上有余作用，在论文的第二部分我们证明了 当%24A%24是其余不变量的Galois余中心扩张时，%24A%24上有Hopf代数结构当且仅当它的余不变量子双代数是 Hopf代数。
- The concepts of the generalization cleft comodule algebra and thegeneralization H?Galois extension with a nouial basis were due to Masuokaand Doi [MD], they studied the equivalence of them and the dual case. Butthey didn? Masuoka和Doi[MD]给出了广义cleft余模代数和具有一个正规基的广义H-Galois扩张的概念，他们研究了二者的等价及对偶情形，但没有涉及到Hopfcrossed积或余积。
- It is well known that an extension field is a linear space over basic field, when the extension field is a Galois extension, every Galois action can be seen a linear transformation. 我们可以认为扩张域就是基域上的线性空间,当这个域扩张是Galois扩张时,每个Galois作用可以看作上述线性空间的线性变换。
