曲线的奇θ特征刻划
Characterizing Curves by their odd Theta-characteristics
摘要:
证明了一般标准曲线是由切其θ-特征的有限超平面集唯一确定的,并证明了稳定自旋曲线的模空间的几何和组合性质,这些性质起着至关重要的作用.
英文摘要:
We show that a general canonical curve is uniquely determined by the finite set of hyperplanes cutting theta-characteristics on it. Geometrical and combinatorial properties of the moduli space of stable spin curves are proved, which play an essential role.
