Geometric survey of subgroups of mapping class groups
نویسنده
چکیده
The theme of this survey is that subgroups of the mapping class group MCG of a finite type surface S can be studied via the geometric/dynamical properties of their action on the Thurston compactification of Teichmüller space T = T ∪PMF , just as discrete subgroups of the isometries of hyperbolic space Hn can be studied via their action on compactified hyperbolic space H n = Hn ∪ S ∞ . 2000 Mathematics Subject Classification: 30F60, 57M50

On rational groups with Sylow 2-subgroups of nilpotency class at most 2
A finite group $G$ is called rational if all its irreducible complex characters are rational valued. In this paper we discuss about rational groups with Sylow 2-subgroups of nilpotency class at most 2 by imposing the solvability and nonsolvability assumption on $G$ and also via nilpotency and nonnilpotency assumption of $G$.
متن کاملGroups with one conjugacy class of non-normal subgroups - a short proof
For a finite group $G$ let $nu(G)$ denote the number of conjugacy classes of non-normal subgroups of $G$. We give a short proof of a theorem of Brandl, which classifies finite groups with $nu(G)=1$.
متن کاملExistence Results of best Proximity Pairs for a Certain Class of Noncyclic Mappings in Nonreflexive Banach Spaces Polynomials
Introduction Let be a nonempty subset of a normed linear space . A self-mapping is said to be nonexpansive provided that for all . In 1965, Browder showed that every nonexpansive self-mapping defined on a nonempty, bounded, closed and convex subset of a uniformly convex Banach space , has a fixed point. In the same year, Kirk generalized this existence result by using a geometric notion of ...
متن کاملQuasi-homomorphisms on Mapping Class Groups
We refine the construction of quasi-homomorphisms on mapping class groups. It is useful to know that there are unbounded quasihomomorphisms which are bounded when restricted to particular subgroups since then one deduces that the mapping class group is not boundedly generated by these subgroups. In this note we enlarge the class of such subgroups. The generalization is motivated by consideratio...
متن کاملSubgroups of Mapping Class Groups Generated by Three Dehn Twists
It has been shown that the mapping class group of a genus g ≥ 2 closed surface can be generated by 2g + 1 Dehn twists. Little is known, however, about the structure of those mapping class groups. This paper is an attempt to explain the structure of subgroups of the mapping class group of a closed surface of genus g ≥ 2 which are generated by three Dehn twists. 1 Background and Notation This pap...
