摘要：

Inside the moduli space of curves of genus 2 with two marked points, we consider the loci of curves admitting a map to P1 of degree d totally ramified over the two marked points, for d= 2. Such loci have codimension two. We compute the class of their closures in the moduli space of stable curves. Several results will be deduced from this computation.
