Tame characters and ramification of finite flat group schemes Original Research Article

In this paper, for a complete discrete valuation field K of mixed characteristic (0,p) and a finite flat group scheme image of p-power order over image, we determine the tame characters appearing in the Galois representation image in terms of the ramification theory of Abbes and Saito, without any restriction on the absolute ramification index of K or the embedding dimension of image.
