论文摘要
在本文中,我们表明,在共同性品种的背景下,中央元素的函数是可以代表的。此外,我们使用中央元素的理论来建立fp-coextensive品种的标准,该品种可以根据一个发电机上的自由代数的不可塑性来决定Gaeta Topos是否对不可分解的对象进行分类。
In this paper we show that within the context of coextensive varieties, the functor of central elements is representable. In addition, we use the theory of central elements to establish a criterion for fp-coextensive varieties that allows to decide whether the Gaeta Topos classifies indecomposable objects in terms of the indecomposability of the free algebra on one generator.
