赋值环的Frobenius分裂与中心的$F$ -奇性

Frobenius splitting of valuation rings and $F$-singularities of centers

Rankeya Datta

摘要:

利用Knaf和Kuhlmann的一个局部单值化结果,证明了素特征完备基域上函数域的Abhyankar赋值的赋值环是Frobenius分裂的.我们证明,行为足够良好的中心的弗罗贝纽斯分裂提升为赋值环的弗罗贝纽斯分裂。我们还研究了以任意的素特征的诺特域为中心的估值的性质。与[arXiv:1507.06009]不同,本文强调了中心在控制素特征赋值环的Frobenius性质中的作用.

英文摘要:

Using a local monomialization result of Knaf and Kuhlmann, we prove that the valuation ring of an Abhyankar valuation of a function field over a perfect ground field of prime characteristic is Frobenius split. We show that a Frobenius splitting of a sufficiently well-behaved center lifts to a Frobenius splitting of the valuation ring. We also investigate properties of valuations centered on arbitrary Noetherian domains of prime characteristic. In contrast to [arXiv:1507.06009], this paper emphasizes the role of centers in controlling Frobenius properties of valuations rings in prime characteristic.
