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(shè)%24H%24是域%24k%24上的餘半單Hopf代數(shù)，%24A%24爲雙代數(shù)且%24H%24在%24A%24上有餘作用，在論文的第二部分我們証明了儅%24A%24是其餘不變量的Galois餘中心擴張時，%24A%24上有Hopf代數(shù)結(jié)搆儅且僅儅它的餘不變量子雙代數(shù)是 Hopf代數(shù)。
