论文摘要
我们证明，任何henselian离散估值的残留特征$ p> 0 $是$ f_p $ - 矢量空间的滤过组的渐变定位者。我们定义了每个分级商的角色组的注入，以使用cotangent络合物定义的扭曲的cotangent空间。
We prove that the graded quotients of the filtration by ramification groups of any henselian discrete valuation field of residue characteristic $p>0$ are $F_p$-vector spaces. We define an injection of the character group of each graded quotient to a twisted cotangent space defined using a cotangent complex.
