Morita某些结果的几何证明
Geometric Proofs of Some Results of Morita
摘要：
本文给出了S.森田这些结果涉及某些二维上同调类的各种模空间的曲线。我们还给出了几何解释的第四个结果的森田。这项工作的动机之一是为了方便应用这些结果在我们的工作（准备）的阿拉克洛夫几何的模空间的曲线。
英文摘要：
In this note we give geometric formulations and proofs of three results of S. Morita. These results relate certain two dimensional cohomology classes of various moduli spaces of curves. We also give a geometric interpretation of a fourth result of Morita. One motivation of this work is to facilitate the application of these results in our work (in preparation) on the Arakelov geometry of moduli spaces of curves.
