Automorphisms of Harbater–Katz–Gabber curves

© 2016, Springer-Verlag Berlin Heidelberg. Let k be a perfect field of characteristic p> 0 , and let G be a finite group. We consider the pointed G-curves over k associated by Harbater, Katz, and Gabber to faithful actions of G on k[[t]] over k. We use such “HKG G-curves” to classify the automorp...
