摘要

引入并使用Schreier基证明了斜多项式环是自由理想环，即其单边理想没有唯一秩的环，以及计算单边理想的秩和相应基的描述。后一个事实，即所谓的Schreier-Lewin公式（Lewin Trans.Am.Math.Soc.14455–465 1969），是确定完美局部化的模类型的基本工具，它揭示了经典莱维特代数、偏斜多项式环和自由结合代数之间的紧密联系。

Skew Polynomial Rings: the Schreier Technique

Schreier bases are introduced and used to show that skew polynomial rings are free ideal rings, i.e., rings whose one-sided ideals are free of unique rank, as well as to compute a rank of one-sided ideals together with a description of corresponding bases. The latter fact, a so-called Schreier-Lewin formula (Lewin Trans. Am. Math. Soc. 145, 455–465 1969), is a basic tool determining a module type of perfect localizations which reveal a close connection between classical Leavitt algebras, skew polynomial rings, and free associative algebras.
