平面曲线的紧模

Compact moduli of plane curves

Paul Hacking

摘要:

我们构造了d次平面曲线的模空间的紧化M_d。我们把平面曲线C看作一个曲面因子对(P^2,C),并把M_d定义为(X,D)对的模空间,其中X是平面的退化。证明了当d不能被3整除时,层叠M_d是光滑的,退化曲面X可以被明确地描述.

英文摘要:

We construct a compactification M_d of the moduli space of plane curves of degree d. We regard a plane curve C as a surface-divisor pair (P^2,C) and define M_d as a moduli space of pairs (X,D) where X is a degeneration of the plane. We show that, if d is not divisible by 3, the stack M_d is smooth and the degenerate surfaces X can be described explicitly.
