重新审视关口-须和理论

Sekiguchi-Suwa theory revisited

Ariane Mézard, Matthieu Romagny, Dajano Tossici

摘要:

我们提出了一个帐户的建设S。Sekiguchi和N. Suwa的仿射光滑群方案的循环等距线的Kummer和Artin-Schreier-Witt同构。我们完成了任意基环上的构造。我们延长报表的一些结果的形式,以适应进一步调查的模型组计划的根的单位。

英文摘要:

We present an account of the construction by S. Sekiguchi and N. Suwa of a cyclic isogeny of affine smooth group schemes unifying the Kummer and Artin-Schreier-Witt isogenies. We complete the construction over an arbitrary base ring. We extend the statements of some results in a form adapted to a further investigation of the models of the group schemes of roots of unity.
