Puiironx幺半群的原子性与因子分解

Atomicity and Factorization of Puiseux Monoids

Marly Gotti

摘要:

一个Puironx幺半群是有理数的非负锥的一个加法子幺半群。虽然Puietrix幺半群是无挠秩幺半群,但它们的原子结构丰富且高度复杂。因此,它们一直是交换代数和因式分解理论中构造关键例子的重要对象。在1974年,安妮·格拉姆斯利用一个Puienix幺半群构造了第一个不满足ACCP的原子域的例子,反驳了科恩关于每个原子域都满足ACCP的猜想。甚至在最近,Jim Coykendall和Felix Gotti已经使用Puironix幺半群来构造第一个具有非原子幺半群代数(域上)的原子幺半群,回答了Robert Gilmer在20世纪80年代提出的一个问题。本论文主要研究Puietrix幺半群的原子结构和因式分解理论。在这里我们建立了一个Puietrix幺半群是原子幺半群(或满足ACCP)的各种充分条件.我们对两个最重要的原子性质做同样的事情:有限分解性质和有界分解性质。然后,我们比较这四个原子性质的背景下,Puietrix幺半群。这使我们能够构建和研究几类Puietrix幺半群具有不同的原子结构。我们的调查提供了足够的证据,相信类Puiiiix幺半群是最简单的类,有足够的复杂性,找到幺半群满足几乎每一个基本的原子行为。

英文摘要:

A Puiseux monoid is an additive submonoid of the nonnegative cone of rational numbers. Although Puiseux monoids are torsion-free rank-one monoids, their atomic structure is rich and highly complex. For this reason, they have been important objects to construct crucial examples in commutative algebra and factorization theory. In 1974 Anne Grams used a Puiseux monoid to construct the first example of an atomic domain not satisfying the ACCP, disproving Cohn's conjecture that every atomic domain satisfies the ACCP. Even recently, Jim Coykendall and Felix Gotti have used Puiseux monoids to construct the first atomic monoids with monoid algebras (over a field) that are not atomic, answering a question posed by Robert Gilmer back in the 1980s. This dissertation is focused on the investigation of the atomic structure and factorization theory of Puiseux monoids. Here we established various sufficient conditions for a Puiseux monoid to be atomic (or satisfy the ACCP). We do the same for two of the most important atomic properties: the finite-factorization property and the bounded-factorization property. Then we compare these four atomic properties in the context of Puiseux monoids. This leads us to construct and study several classes of Puiseux monoids with distinct atomic structure. Our investigation provides sufficient evidence to believe that the class of Puiseux monoids is the simplest class with enough complexity to find monoids satisfying almost every fundamental atomic behavior.
