Hasse-Schmidt Derivations and Coefficient Fields in Positive Characteristics
摘要:
我们展示了如何表示任何Hasse-Schmidt推导代数的有限数量的自然假设下。作为应用,我们得到了具有正特征的正则局部环的完备化的系数域
英文摘要:
We show how to express any Hasse-Schmidt derivation of an algebra in terms of a finite number of them under natural hypothesis. As an application, we obtain coefficient fields of the completion of a regular local ring of positive characteristic in terms of Hasse-Schmidt derivations
