Curvature and hyperbolicity of surfaces

, 2004
An Aleksandrov surface is a generalization of two-dimensional Riemannian manifolds, and it is known by a theorem of A. Huber (1960) that every open simply connected Aleksandrov surface is conformally equivalent either to the unit disc (hyperbolic case ...

Värimallien Gromov hyperbolisuus käyttäen iso-hue dataa

In this thesis we explore the hyperbolic nature of color models. We will apply the notion of Gromov hyperbolicity over color data. Mikhail Gromov introduced a new notion of hyperbolicity, known as the Gromov delta, in 1987.

Gromov Hyperbolicity in Directed Graphs [PDF]

Symmetry, 2020
In this paper, we generalize the classical definition of Gromov hyperbolicity to the context of directed graphs and we extend one of the main results of the theory: the equivalence of the Gromov hyperbolicity and the geodesic stability. This theorem has potential applications to the development of solutions for secure data transfer on the internet.

Gromov Hyperbolicity of Riemann Surfaces [PDF]

Acta Mathematica Sinica, English Series, 2006
In this paper we study the hyperbolicity in the Gromov sense of Riemann surfaces. We deduce the hyperbolicity of a surface from the hyperbolicity of its "building block components". We also prove the equivalence between the hyperbolicity of a Riemann surface and the hyperbolicity of some graph associated with it.
