关于代数数域中非主序运算的一个精确结果

A precise result on the arithmetic of non-principal orders in algebraic number fields

Andreas Philipp

摘要:

令$R$是代数数域中的阶。如果$R$是主序,则关于它的算术有许多显式的结果.其中,$R$是半阶乘的当且仅当$R$的类群最多有两个元素。对非主要订单的了解要少得多。利用一种新的半群理论方法,研究了代数数域中非主序的半因子性及进一步的算术性质。

英文摘要:

Let $R$ be an order in an algebraic number field. If $R$ is a principal order, then many explicit results on its arithmetic are available. Among others, $R$ is half-factorial if and only if the class group of $R$ has at most two elements. Much less is known for non-principal orders. Using a new semigroup theoretical approach, we study half-factoriality and further arithmetical properties for non-principal orders in algebraic number fields.
