.给定一个数值半群H_∞(Z ≥ 0,+),考虑半群H的亏格为g的光滑曲线的轨迹M_Hg,1.我们证明了对亏格g ≤ 6的所有半群H,轨迹MHg,1是不可约的,并且对除可能两个之外的所有半群H,轨迹MHg,1是稳定有理的.
. Given a numerical semigroup H ⊆ ( Z ≥ 0 , +), we consider the locus M Hg, 1 of smooth curves of genus g with a marked Weierstrass point of semi-group H . We show that for all semigroups H of genus g ≤ 6 the locus M Hg, 1 is irreducible and that for all but possibly two such semigroups it is stably rational.
