余模的分解

运用了独特的分解方式,把域上的任意余模唯一分解成不可分的闭余子模的直和。

Decomposition of Comodules

It has been proved, using a special approach, that any comodules over a field can be uniquely decomposed into the direct sum of closed indecomposable subcomodules.

有限维双代数的特征

讨论域Ｋ上的有限维Ｈｏｐｆ代数的ａｎｔｉｐｏｄｅ和积分的关系，证明了Ｋａｐｌａｎｓｋｙ猜测的等价命题，并且给出了有限维双代数是Ｈｏｐｆ代数的充要条件．
