As for qt singularities seeming to only work in char. 0, there's a notion of "tame cyclic quotient singularities" valid over any dvr which exhibits many features in comment with char. 0 (e.g., minimal regular resolution related to the usual continued fraction stuff): see Def. 2.3.6 and section 2.4 of my paper with Edixhoven & Stein called "$J_1(p)$ has connected fibers". | |
