Resum
The goal of this talk is to give a classification of the reduction of genus-3 curves whose automorphism group contains a subgroup isomorphic to the Klein group, in the lines of Liu's classification of the reduction of genus-2 curves. We will first compute all possible reduction types, and then characterize when each case is attained in terms of the valuations of the coefficients of a normalized model of the curve.
