余交换双代数范畴的S-原模性
S-protomodularity of the category of cocommutative bialgebras
摘要:
证明了在任何对称幺半范畴(具有均衡器)中的余交换双代数范畴是关于余交换双代数的一类特殊分裂扩张的S-原模范畴.我们还得到了著名的“部分”Smithis Huq条件,即两个S-等价关系只要在Huq意义下交换,它们就相互集中.
英文摘要:
We prove that the category of cocommutative bialgebras in any symmetric monoidal category (that has equalizers) is an S-protomodular category with respect to a particular class of split extensions of cocommutative bialgebras. We also obtain the ``partial'' well-known Smith is Huq condition, meaning that two S-equivalence relations centralize each other as soon as the normal subobjects associated with them commute in the sense of Huq.
