Right-angled Artin groups and finite subgraphs of curve graphs
نویسندگان
چکیده
We show that for a sufficiently simple surface S, if a right-angled Artin group A(Γ) embeds into Mod(S) then Γ embeds into the curve graph C(S) as an induced subgraph. When S is sufficiently complicated, there exists an embedding A(Γ) → Mod(S) such that Γ is not contained in C(S) as an induced subgraph.

On Right-angled Artin Groups without Surface Subgroups
We study the class N of graphs, the right-angled Artin groups defined on which do not contain surface subgroups. We prove that a presumably smaller class N ′ is closed under amalgamating along complete subgraphs, and also under adding bisimplicial edges. It follows that chordal graphs and chordal bipartite graphs belong to N ′.
متن کاملSurface Subgroups of Right-Angled Artin Groups
We consider the question of which right-angled Artin groups contain closed hyperbolic surface subgroups. It is known that a right-angled Artin group A(K) has such a subgroup if its defining graph K contains an n-hole (i.e. an induced cycle of length n) with n ≥ 5. We construct another eight “forbidden” graphs and show that every graph K on ≤ 8 vertices either contains one of our examples, or co...
متن کاملRight-angled Mock Reflection and Mock Artin Groups
We define a right-angled mock reflection group to be a group G acting combinatorially on a CAT(0) cubical complex such that the action is simply-transitive on the vertex set and all edge-stabilizers are Z2. We give a combinatorial characterization of these groups in terms of graphs with local involutions. Any such graph Γ not only determines a mock reflection group, but it also determines a rig...
متن کاملThe geometry of purely loxodromic subgroups of right-angled Artin groups
We prove that finitely generated purely loxodromic subgroups of a right-angled Artin group A(Γ) fulfill equivalent conditions that parallel characterizations of convex cocompactness in mapping class groups Mod(S). In particular, such subgroups are quasiconvex in A(Γ). In addition, we identify a milder condition for a finitely generated subgroup of A(Γ) that guarantees it is free, undistorted, a...
متن کاملThe geometry of the curve graph of a right-angled Artin group
We develop an analogy between right-angled Artin groups and mapping class groups through the geometry of their actions on the extension graph and the curve graph respectively. The central result in this paper is the fact that each right-angled Artin group acts acylindrically on its extension graph. From this result we are able to develop a Nielsen–Thurston classification for elements in the rig...
