曲面同态群的同调与Morita的一个问题

The homology of surface diffeomorphism groups and a question of Morita

Jonathan Bowden

摘要:

我们回答了一个问题所提出的森田关于非平凡的某些次级特征类的表面丛。在这样做的时候,我们很自然地导致表明,一种形式的哈勒稳定性举行的表面单同态群的同调小程度。

英文摘要:

We answer a question posed by Morita concerning the non-triviality of certain secondary characteristic classes for surface bundles. In doing so we are naturally led to show that a form of Harer stability holds for surface diffeomorphism groups in homology of small degree.
