AI总结:

本文提出通过仿射和超仿射代数理论统一表示交换环和布尔环,并探讨了其与布尔集合及多维布尔代数的关系。

摘要:

我们提出了一种统一的框架,用于通过仿射代数理论表示交换环,通过超仿射代数理论表示布尔环。这导致了这些理论与相应交换环和布尔环之间的范畴等价性。然后我们分析了在布尔环$B$上仿射理论的模型,并将其与超仿射理论的模型(即众所周知的$B$-集合)进行比较。我们提出了两个新的特征化:第一个将这些模型定义为带有布尔环作用的布尔向量空间;第二个则以类似于$B$-集合的方式提供了一种表示方法。最后,我们建立了超仿射理论与多维布尔代数之间的联系,这是一种最近引入的布尔代数泛化。

英文摘要:

We present a unified framework for representing commutative rings through affine algebraic theories and Boolean rings through hyperaffine algebraic theories. This yields categorical equivalences between these theories and, respectively, commutative rings and Boolean rings. We then analyse models of affine theories over a Boolean ring $B$, comparing them with the models of hyperaffine theories, the well-known $B$-sets. Two novel characterisations are presented: the first defines these models as Boolean vector spaces equipped with an action of the Boolean ring; the second provides a representation in terms of sheaves, in analogy with $B$-sets. Finally, we establish a connection between hyperaffine theories and multidimensional Boolean algebras, a recently introduced generalisation of Boolean algebras.
