赋值半环

Valuation Semirings

Peyman Nasehpour

摘要:

本文的主要内容是一般地介绍赋值半环,特别是离散赋值半环。为了做到这一点,我们首先定义估值图并对其进行研究。然后利用赋值映射定义了赋值半环,证明了乘可消半环是赋值半环当且仅当它的理想是全包含序的。证明了如果赋值半环的唯一极大理想是可减的,则它是整闭的。最后,我们引入了离散赋值半环,并证明了半环是离散赋值半环当且仅当它是具有非零唯一极大理想的乘可消主理想半环。证明了离散赋值半环是Gauss半环当且仅当它的唯一极大理想是可减的。

英文摘要:

The main scope of this paper is to introduce valuation semirings in general and discrete valuation semirings in particular. In order to do that, first we define valuation maps and investigate them. Then we define valuation semirings with the help of valuation maps and prove that a multiplicatively cancellative semiring is a valuation semiring if and only if its ideals are totally ordered by inclusion. We also prove that if the unique maximal ideal of a valuation semiring is subtractive, then it is integrally closed. We end this paper by introducing discrete valuation semirings and show that a semiring is a discrete valuation semiring if and only if it is a multiplicatively cancellative principal ideal semiring possessing a nonzero unique maximal ideal. We also prove that a discrete valuation semiring is a Gaussian semiring if and only if its unique maximal ideal is subtractive.
