赋值分支与局部环

Ramification of valuations and local rings

Steven Dale Cutkosky

摘要:

本文研究了优良局部环上分歧的双有理性质。我们扩展了作者与Olivier Piltant的早期结果,以表明沿着支配二维优秀局部局部环的无缺陷扩张的赋值,强局部单名化是真实的。我们还得到了一般结果的结构的扩张的相关分次环沿赋值,并表明,不变量α和β的稳定形式的二维扩张的特征p的作者和Olivier Piltant最终不是常数。

英文摘要:

In this paper we consider birational properties of ramification in excellent local rings. We extend earlier results of the author with Olivier Piltant to show that strong local monomialization is true along a valuation dominating a defectless extension of two dimensional excellent local rings. We also obtain general results on the structure of the extension of associated graded rings along a valuation, and show that the invariants alpha and beta of stable forms of two dimensional extensions in characteristic p of the author and Olivier Piltant are not eventually constant.
