On the Glimm functional for general hyperbolic systems

open access: yes, 2011
In this note we discuss the features of a quadratic interaction potential for first order hyperbolic systems in one space dimension, aiming to suggest the need of defining a non local functional depending on the global wave structure of the solution in ...

Interaction estimates and Glimm functional for general hyperbolic systems

open access: yes, 2003
We consider the problem of writing Glimm type interaction estimates for the hyperbolic system \begin{equation}\label{E:abs0} u_t + A(u) u_x = 0. \end{equation} %only assuming that $A(u)$ is strictly hyperbolic. The aim of these estimates is to prove that

A characterization of hyperbolic spaces

open access: yes, 2007
We show that a geodesic metric space, and in particular the Cayley graph of a finitely generated group, is hyperbolic in the sense of Gromov if and only if intersections of any two metric balls balls is itself "almost" a metric ball.

Generalized Hyperbolic Distributions and Brazilian Data [PDF]

open access: yes
The aim of this paper is to discuss the use of the Generalized Hyperbolic Distributions to fit Brazilian assets returns. Selected subclasses are compared regarding goodness of fit statistics and distances.
