Parabolicity and Cheeger's constant on graphs

Á Martínez-Pérez, JM Rodríguez - Revista de la Real Academia de …, 2024 - Springer
Herein we study p-parabolicity on graphs. We prove that if a uniform graph satisfies the
(Cheeger) isoperimetric inequality, then it is non-p-parabolic for every 1< p<∞. Moreover …

Cheeger isoperimetric constant of Gromov hyperbolic manifolds and graphs

A Martínez-Pérez, JM Rodríguez - … in Contemporary Mathematics, 2018 - World Scientific
In this paper, we study the relationship of hyperbolicity and (Cheeger) isoperimetric
inequality in the context of Riemannian manifolds and graphs. We characterize the …

Stability of p‐parabolicity under quasi‐isometries

A Granados, D Pestana, A Portilla… - Mathematische …, 2022 - Wiley Online Library
Kanai proved the stability under quasi‐isometries of numerous global properties (including
existence of Green's function, ie, non‐parabolicity) between Riemannian manifolds of …

A note on isoperimetric inequalities of Gromov hyperbolic manifolds and graphs

Á Martínez-Pérez, JM Rodríguez - Revista de la Real Academia de …, 2021 - Springer
We study in this paper the relationship of isoperimetric inequality and hyperbolicity for
graphs and Riemannian manifolds. We obtain a characterization of graphs and Riemannian …

Isoperimetric inequalities in Riemann surfaces and graphs

Á Martínez-Pérez, JM Rodríguez - The Journal of Geometric Analysis, 2021 - Springer
A celebrated theorem of Kanai states that quasi-isometries preserve isoperimetric
inequalities between uniform Riemannian manifolds (with positive injectivity radius) and …

Stability of the volume growth rate under quasi-isometries

A Granados, D Pestana, A Portilla… - Revista Matemática …, 2020 - Springer
Kanai proved powerful results on the stability under quasi-isometries of numerous global
properties (including the volume growth rate) between non-bordered Riemannian manifolds …

On p-parabolicity of Riemannian manifolds and graphs

A Martinez-Perez, JM Rodriguez - Revista Matemática Complutense, 2022 - Springer
Kanai proved that quasi-isometries between Riemannian manifolds with bounded geometry
preserve many global properties, including the existence of Green's function, ie, non …
