因式分解范畴

The Category of Factorization

Brandon Goodell, Sean K. Sather-Wagstaff

摘要:

本文引入并研究了一个乘性的、可交换的、可消的、预序幺半群$A$的分解范畴,记为$\mathcal{F}(A)$。$\mathcal{F}(A)$的对象是$A$的元素的因式分解,并且$\mathcal{F}(A)$中的态射编码因式分解之间的组合相似性和差异。我们特别注意整除预序和幺半群$A=D\setminus\{0\}$,其中$D$是一个整环。在其他结果中,我们证明了$\mathcal{F}(A)$是一个对称的,严格的幺半范畴弱等价和计算的相关范畴的分数通过反转的弱等价。同时,我们也利用这个结构来刻画整环的各种分解性质:原子性,唯一分解,等等。

英文摘要:

We introduce and investigate the category of factorization of a multiplicative, commutative, cancellative, pre-ordered monoid $A$, which we denote $\mathcal{F}(A)$. The objects of $\mathcal{F}(A)$ are factorizations of elements of $A$, and the morphisms in $\mathcal{F}(A)$ encode combinatorial similarities and differences between the factorizations. We pay particular attention to the divisibility pre-order and to the monoid $A=D\setminus\{0\}$ where $D$ is an integral domain. Among other results, we show that $\mathcal{F}(A)$ is a symmetric and strict monoidal category with weak equivalences and compute the associated category of fractions obtained by inverting the weak equivalences. Also, we use this construction to characterize various factorization properties of integral domains: atomicity, unique factorization, and so on.
