WebThe book is suitable for graduate students. A Primer on Mapping Class Groups begins by explaining the main group-theoretical properties of Mod(S), from finite generation by Dehn twists and low-dimensional homology to the Dehn-Nielsen-Baer theorem. WebThe group is the mapping class group of S, denoted by Mod(S). This group is defined by the isotopy classes of orientation-preserving homeomorphism from S to itself. Equivalently, Mod(S) may be defined using diffeomorphisms instead of homeomorphisms or homotopy classes instead of isotopy classes. The space is the Teichmüller space of S, Teich(S).
WebThe Birman exact sequence: the forgetful map For this, we will consider the pure mapping class group PMCG(S). This is the subgroup of MCG(S) that xes each puncture of S. Let S = S g;p with p 1 and choose a puncture y. If we \forget" the puncture y we get the surface S g;p 1. Suppose that f is a mapping class in PMCG(S). Since f is a pure
