Bertin, José; Mézard, Ariane Formal deformations of wildly ramified coverings of algebraic curves. (Déformations formelles des revêtements sauvagement ramifiés de courbes algébriques.) (French) Zbl 0993.14014 Invent. Math. 141, No. 1, 195-238 (2000). The authors study the formal moduli of wildly ramified Galois coverings. They determine the dimensions of the global and local versal deformation rings.
