代数曲线上的次正则点

Subcanonical points on algebraic curves

Evan M. Bullock

摘要:

亏格为g的代数曲线上的一点是次正则的,如果某个正则微分仅在该点处为零,且重数为2g-2。次规范点是指Weierstrass点,我们计算了具有标记次规范点的曲线的模空间的每个分支的一般点处的相关间隙序列。我们还构造了具有其他间隙序列的次典范点作为某些循环覆盖的分歧点。

英文摘要:

A point of an algebraic curve of genus g is subcanonical if some regular differential vanishes only at that point, with multiplicity 2g-2. Subcanonical points are Weierstrass points, and we compute the associated gap sequence at a general point of each component of the moduli space of curves with marked subcanonical point. We also construct subcanonical points with other gap sequences as ramification points of certain cyclic covers.
