Injections of mapping class groups

We construct new monomorphisms between mapping class groups of surfaces. The first family of examples injects the mapping class group of a closed surface into that of a different closed surface. The second family of examples are defined on mapping class groups of oncepunctured surfaces and have quite curious behaviour. For instance, some pseudo-Anosov elements are mapped to multi-twists. Neithe...

From braid groups to mapping class groups

This paper is a survey of some properties of the braid groups and related groups, that lead to questions on mapping class groups. AMS Subject Classification: Primary 20F36. Secondary 57M99, 57N05.

Homomorphisms from Mapping Class Groups

This paper concerns rigidity of the mapping class groups. We show that any homomorphism φ : Modg → Modh between mapping class groups of closed orientable surfaces with distinct genera g > h is trivial if g ≥ 3 and has finite image for all g ≥ 1. Some implications are drawn for more general homomorphs of these groups.

Order automatic mapping class groups

We prove that the mapping class group of a compact surface with a finite number of punctures and non-empty boundary is order automatic. More precisely, the group is right-orderable, has an automatic structure as described by Mosher, and there exists a finite state automaton that decides, given the Mosher normal forms of two elements of the group, which of them represents the larger element of t...
