仿 Hopf 代数胚及其循环上同调
K理论与同调

摘要
我们引入「仿 Hopf 代数胚(para-Hopf algebroid)」的概念，并仿照 Connes-Moscovici 关于 Hopf 代数的循环上同调来定义其循环上同调。仿 Hopf 代数胚与 Hopf 代数胚密切相关但有所不同。其定义的动机在于试图一般地定义 Hopf 代数胚的循环上同调理论。我们证明许多 Hopf 代数结构，包括 Connes-Moscovici 代数 ，都是仿 Hopf 代数胚。

备注
Final version to appear in Letters in Mathematical Physics. The name of the article has been changed. Our new class of bialgebroids are now called ``para-Hopf algebroids''. One new example of bialgebroids, due to Connes and Moscovici, are shown to satisfy our axioms of para-Hopf algebroids
