内容简介

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.

前言/序言

Transformation groups have played a fundamental role in many areas of mathematics such as differential geometry, geometric topology, algebraic topology, algebraic geometry, number theory. One of the basic reasons for their importance is that symmetries are described by groups (or rather group actions). Indeed, the existence of group actions makes the spaces under study more interesting, and properties of groups can also be understood better by studying their actions on suitable spaces.
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.
The notion of V-manifolds was first introduced by Satake in 1956 in the con-text of locally symmetric spaces and automorphic forms. V-manifolds were reintroduced and renamed orbifolds by Thurston near the end of 1978 in connection with the Thurston geometrization conjecture on the geometry of three dimensional manifolds. Basically, orbifolds are locally quotients of smooth manifolds by finite groups. Besides arising from transformation groups, many natural spaces in number theory and algebraic geometry are orbifolds.
