摘要

In this dissertation we expand on the study of taun-factorizations or generalized integer factorizations introduced by D.D. Anderson and A. Frazier and examined by S. Hamon. Fixing a non-negative integer n, a taun-factorization of a nonzero nonunit integer a is a factorization of the form a = lambda· a1·a2··· at where t ≥ 1, lambda = 1 or -1 and the nonunit nonzero integers a1, a2, ..., at satisfy a1 ≡ a2 ≡ ... ≡ at mod n. The taun-factorizations of the form a = a1· a2···at (that is, without a leading -1) are called reduced tau n-factorizations. While similarities exist between the tau n-factorizations and the reduced taun-factorizations, the study of one type of factorization does not elucidate the other. This work serves to compare the taun-factorizations of the integers with the reduced taun-factorizations in Z and the taun-factorizations in N .;One of the main goals is to explore how the Fundamental Theorem of Arithmetic extends to these generalized factorizations. Results regarding the tau n-factorizations in Z have been discussed by S. Hamon. Using different methods based on group theory we explore similar results about the reduced tau n-factorizations in Z and the taun-factorizations in N . In other words, we identify the few values of n for which every integer can be expressed as a product of the irreducible elements related to these factorizations and indicate when one can do so uniquely.;Using our approach the taun-factorizations in N are shown to be the easiest to describe. In Z the taun-factorizations pose less of a challenge than the reduced taun-factorizations.

Hamon)检查。固定非负整数n时,非零非单位整数a的牛顿因子分解是形式为a = lambda·a1·a2···的因式分解,其中t≥1,lambda = 1或-1而非单位非零整数a1,a2,...,在mod n处满足a1≡a2≡...≡。 a = a1·a2··at(即没有前导-1)形式的Taun因式分解称为缩减tau n因式分解。尽管tau n因式分解和缩减的taun因式分解之间存在相似性,但对一种因式分解的研究并未阐明另一种因式分解。这项工作旨在比较整数的牛顿因式分解与Z中的减少的牛顿因式分解和N中的牛顿因式分解。主要目标之一是探索算术基本定理如何扩展到这些广义因式分解。 S. Hamon已讨论了有关Z中tau n分解的结果。使用基于群论的不同方法,我们探索了有关Z中的还原tau n分解和N中的taun分解的相似结果。换句话说,我们确定n的几个值,每个整数都可以表示为与这些因式分解相关的不可约元素的乘积,并指出何时可以唯一地实现。;使用我们的方法,显示了N中的Taun因式分解最容易描述。在Z中,与减少的Taun分解相比,Taun分解带来的挑战更少。
