摘要翻译:
在自旋曲线的模空间S_g(即具有θ特征的g属光滑曲线)的Cornalba紧实杆S_g中,我们确定了光滑轨迹和正则奇点轨迹。此外,还证明了多元正则形的提升结果:\bar S_g光滑轨迹上的每一个多元正则形全纯推广到\bar S_g的一个去奇异。

英文摘要:
We determine the smooth locus and the locus of canonical singularities in the Cornalba compactification \bar S_g of the moduli space S_g of spin curves, i.e., smooth curves of genus g with a theta characteristic. Moreover, the following lifting result for pluricanonical forms is proved: Every pluricanonical form on the smooth locus of \bar S_g extends holomorphically to a desingularisation of \bar S_g.
