Loxodromic elements in big mapping class groups via the Hooper–Thurston–Veech construction
نویسندگان
چکیده
Let $S$ be an infinite-type surface and $p\in S$. We show that the Thurston-Veech construction for pseudo-Anosov elements, adapted surfaces, produces infinitely many loxodromic elements action of $Mod(S;p)$ on loop graph $L(S;p)$ do not leave any finite-type subsurface $S'\subset S$ invariant. Moreover, in language Bavard-Walker, Thurston-Veech's weight. As a consequence Bavard Walker's work, subgroup containing two "Thurston-Veech loxodromics" different weight has infinite-dimensional space non-trivial quasimorphisms.

متن کاملRoots in the mapping class groups
The purpose of this paper is the study of the roots in the mapping class groups. Let Σ be a compact oriented surface, possibly with boundary, let P be a finite set of punctures in the interior of Σ, and let M(Σ,P) denote the mapping class group of (Σ,P). We prove that, if Σ is of genus 0, then each f ∈ M(Σ) has at most one m-root for all m ≥ 1. We prove that, if Σ is of genus 1 and has non-empt...
متن کاملLoxodromic Elements in the Cyclic Splitting Complex and Their Centralizers
We show that an outer automorphism acts loxodromically on the cyclic splitting complex if and only if it has a filling lamination and no generic leaf of the lamination is carried by a vertex group of a cyclic splitting. This is the analog for the cyclic splitting complex of HandelMosher’s theorem on loxodromics for the free splitting complex. We also show that such outer automorphisms have virt...
متن کاملConvex Cocompactness in Mapping Class Groups via Quasiconvexity in Right-angled Artin Groups
We characterize convex cocompact subgroups of mapping class groups that arise as subgroups of specially embedded right-angled Artin groups. That is, if the right-angled Artin group G < Mod(S) satisfies certain conditions that imply G is quasi-isometrically embedded in Mod(S), then a purely pseudo-Anosov subgroup H < G is convex cocompact in Mod(S) if and only if it is combinatorially quasiconve...
