我们研究了尖点曲线模空间上一类自然的正规函数,并确定了它们在每一点处的秩。我们证明了在阿贝尔微分对应的分层之外,秩是极大的,而沿着该分层,秩恰好下降一。作为推论,我们描述了相关的双分歧轨迹的局部几何。
英文摘要
We study a natural class of normal functions on the moduli space of pointed curves and determine their rank at every point. We prove that the rank is maximal outside the corresponding stratum of Abelian differentials, while along this stratum it drops by exactly one. As a consequence, we describe the local geometry of the associated double ramification locus.
