cocentral

常見例句

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.
設%24H%24是域%24k%24上的余半單Hopf代數(shù)，%24A%24為雙代數(shù)且%24H%24在%24A%24上有余作用，在論文的第二部分我們證明了當%24A%24是其余不變量的Galois余中心擴張時，%24A%24上有Hopf代數(shù)結(jié)構(gòu)當且僅當它的余不變量子雙代數(shù)是 Hopf代數(shù)。
