Sharp estimates of the Kobayashi metric and Gromov hyperbolicity [PDF]

open access: yes, 2008
26 pages, 3 figures.Let D be a smooth relatively compact and strictly J-pseudoconvex domain in a four dimensional almost complex manifold (M,J). We give sharp estimates of the Kobayashi metric.

Gromov (non-)hyperbolicity of certain domains in $\mathbb{C}^{n}$

open access: yes, 2016
We prove the Gromov non-hyperbolicity with respect to the Kobayashi distance for C1,1-smooth convex domains in C2 which contain an analytic disc in the boundary or have a point of infinite type with rotation symmetry.

Coboundary expansion and Gromov hyperbolicity

open access: yesGroups, Geometry, and Dynamics
We prove that if a compact n -manifold admits a sequence of residual covers that form a coboundary expander in dimension  n-2 , then the manifold has Gromov ...

Stability of Gromov hyperbolicity

open access: yes, 2010
A main problem when studying any mathematical property is to determine its stability, i.e., under what type of perturbations it is preserved. With this aim, here we study the stability of Gromov hyperbolicity, a property which has been proved to be fruitful in many fields.

Acylindrical hyperbolicity of groups acting on trees

open access: yes, 2015
We provide new examples of acylindrically hyperbolic groups arising from actions on simplicial trees. In particular, we consider amalgamated products and HNN-extensions, 1-relator groups, automorphism groups of polynomial algebras, 3-manifold groups and ...
