Let be a surface with either boundary or marked points, equipped with an arbitrary framing. In this note we determine the action of the associated ‘framed mapping class group’ on the homology of relative to its boundary (respectively, marked points), describing the image as the kernel of a certain crossed homomorphism related to classical spin structures. Applying recent work of the authors, we use this to describe the monodromy action of the orbifold fundamental group of a stratum of abelian differentials on the relative periods.

框架映射类组的相对同源表示
让 是具有边界或标记点的表面,并具有任意框架。在本说明中,我们确定关联的“框架映射类组”对相对于其边界(分别是标记点)的距离,将图像描述为与经典自旋结构有关的某种交叉同态的核。应用作者最近的工作,我们用它来描述阿贝尔微分层的球面基本群对相对周期的单峰作用。
