变换群在微分几何、几何拓扑、代数拓扑、代数几何、数论等诸多数学领域起到了基础性的作用。本书包含了2008年两个暑期学校“Transformation Groups and Orbifolds”和“Geometry of Teichmüller Spaces and Moduli Spaces of Curves”的扩展讲义,是相关专业学生和研究人员学习变换群、轨形、Teichmüller空间、映射类群、曲线模空间和相关课题的颇具价值的资料。本书可供数学专业的研究生和高年级本科生阅读,也可供相关领域研究人员参考。

内容推荐

Transformation groups have played a fundamental role in many areas of mathematics such as differential geometry, geometric topology, algebraic topology, algebraic geometry, number theory. Ore of the basic reasons for their importance is that symmetries are described by groups (or rather group actions). Quotients of smooth manifolds by group actions are usually not smooth manifolds. On the other hand, if the actions of the groups are proper, then the quotients are orbifolds. An important example is given by the action of the mapping class groups on the Teichmuller spaces, and the quotients give the moduli spaces of Riemann surfaces (or algebraic curves) and are orbifolds.

This book consists of expanded lecture' notes of two summer schools Transformation Groups and Orbifolds and Geometry of Teichmuller Spaces and Moduli Spaces of Curves in 2008 and will be a valuable source for people to learn transformation groups, orbifolds, Teichmuller spaces, mapping class groups, moduli soaces of curves and related topics.
