In this paper, we define a Cayley–Dickson process for k -coalgebras proving some results that describe the properties of the final coalgebra, knowing the properties of the initial one. Namely, after applying the Cayley–Dickson process for k -coalgebras to a coassociative coalgebra, we obtain a coalternative one. Moreover, the first coalgebra is cocommutative if and only if the final coalgebra is coassociative. Finally we extend these results to a more general approach of D -coalgebras, where D is a k -coalgebra, presenting a class of examples of coalternative (non-coassociative) coalgebras obtained from group D -coalgebras.

可替代的代数
在本文中,我们定义了一个 Cayley-Dickson 过程ķ -coalgebras 证明了一些结果,这些结果描述了最终 coalgebra 的性质,知道初始 coalgebra 的性质。即,在应用 Cayley-Dickson 过程后ķ -coalgebras 到一个 coassociative coalgebra,我们得到一个 coalternative。此外,第一个余代数是协交换的当且仅当最后一个余代数是协合的。最后,我们将这些结果扩展到更一般的方法D - 代数,其中D 是一个ķ -coalgebra,呈现从组中获得的 coalternative (non-coassociative) coalgebras 的一类示例D -代数。
