On the One Class of Hyperbolic Systems [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2006
The classification problem is solved for some type of nonlinear lattices. These lattices are closely related to the lattices of Ruijsenaars-Toda type and define the Bäcklund auto-transformations for the class of two-component hyperbolic systems.

Hyperbolic Methods for Einstein's Equations

open access: yesLiving Reviews in Relativity, 1998
I review evolutionary aspects of general relativity, in particular those related to the hyperbolic character of the field equations and to the applications or consequences that this property entails.

Substantiation of asymptotical solution of weakly nonlinear hyperbolic system

open access: yesLietuvos Matematikos Rinkinys, 2023
A hyperbolic system of first order partial differential equations with small parameter and periodical initial conditions is obtained. The uniformly valid in a long time interval asymptotical solution can be constructed using the averaging along ...

Stable schemes for second-moment turbulent models for incompressible flows

open access: yesComptes Rendus. Mécanique, 2023
A stable scheme is proposed in this paper in order to obtain approximate solutions of second-moment turbulent models for incompressible flows with or without thermal transport equation. The analysis of the convective terms, which includes the solution of

T5 configurations and hyperbolic systems

open access: yesCommunications in Contemporary Mathematics, 2023
In this paper, we study the rank-one convex hull of a differential inclusion associated to entropy solutions of a hyperbolic system of conservation laws. This was introduced in [B. Kirchheim, S. Müller and V. Šverák, Studying Nonlinear PDE by Geometry in Matrix Space (Springer, 2003), Sec.

A Vector Series Solution for a Class of Hyperbolic System of Caputo Time-Fractional Partial Differential Equations With Variable Coefficients

open access: yesFrontiers in Physics, 2021
In this paper, we introduce a series solution to a class of hyperbolic system of time-fractional partial differential equations with variable coefficients. The fractional derivative has been considered by the concept of Caputo.

Computability, noncomputability, and hyperbolic systems [PDF]

open access: yesApplied Mathematics and Computation, 2012
In this paper we study the computability of the stable and unstable manifolds of a hyperbolic equilibrium point. These manifolds are the essential feature which characterizes a hyperbolic system. We show that (i) locally these manifolds can be computed, but (ii) globally they cannot (though we prove they are semi-computable).

Extremal problems for second order hyperbolic systems involving multiple time delays [PDF]

open access: yesArchives of Control Sciences, 2023
Extremal problems for multiple time delay hyperbolic systems are presented. The optimal boundary control problems for hyperbolic systems in which multiple time delays appear both in the state equations and in theNeumann boundary conditions are solved ...

A study of a quasilinear model of the particles of a suspension that are aggregated and settled in an inhomogeneous field

open access: yesVisnik Harkivsʹkogo Nacionalʹnogo Universitetu im. V.N. Karazina. Cepiâ Matematika, Prikladna Matematika i Mehanika, 2020
The mathematical model of the sedimentation process of suspension particles is usually a quasilinear hyperbolic system of partial differential equations, supplemented by initial and boundary conditions.
