摘要
本文详细计算了特征2域上(Z/2)^r的函数代数的Sweedler上同调，所有度数。结果与特征0情形显著不同。然后我们展示了特征p中Kassel与作者在特征零中得到的结果的一个变体，该变体提供了有限群上函数代数情形下第二懒惰上同调群的近乎完整的计算。

备注
With this update we pretty much revert to version 2 (including the old title), for the good reason that this version has been accepted for publication in Comm. Alg. (without part II which appeared in version 3). So this final paper is identical with the published one
