Surface-like boundaries of hyperbolic groups
Benjamin Beeker, Nir Lazarovich
We classify the boundaries of hyperbolic groups that have enough quasiconvex codimension-1 surface subgroups with trivial or cyclic intersections.
Cubical accessibility and bounds on curves on surfaces
Benjamin Beeker, Nir Lazarovich
We bound the size of -dimensional cubulations of finitely presented groups. We apply this bound to obtain acylindrical accessibility for actions on CAT(0) cube complexes and bou…
Stallings folds for CAT(0) cube complexes and quasiconvex subgroups
Benjamin Beeker, Nir Lazarovich
We describe a higher dimensional analogue of the Stallings folding sequence for group actions on CAT(0) cube complexes. We use it to give a characterization of quasiconvex subgroup…
Sphere boundaries of hyperbolic groups
Benjamin Beeker, Nir Lazarovich
We show that a one-ended simply connected at infinity hyperbolic group with enough codimension-1 surface subgroups has . Combined with a result o…
Resolutions of CAT(0) cube complexes and accessibility properties
Benjamin Beeker, Nir Lazarovich
In [4], Dunwoody defined resolutions for finitely presented group actions on simplicial trees, that is, an action of the group on a tree with smaller edge and vertex stabilizers. H…
Compatibility JSJ decomposition of graphs of free abelian groups
Benjamin Beeker
A group G is a vGBS group if it admits a decomposition as a finite graph of groups with all edge and vertex groups finitely generated and free abelian. We describe the compatibilit…
Multiple conjugacy problem in graphs of free abelian groups
Benjamin Beeker
A group G is a vGBS group if it admits a decomposition as a finite graph of groups with all edge and vertex groups finitely generated and free abelian. We prove that the multiple c…
Abelian JSJ decomposition of graphs of free abelian groups
Benjamin Beeker
A group G is a vGBS group if it admits a decomposition as a finite graph of groups with all edge and vertex groups finitely generated and free abelian. We construct the JSJ decompo…
