Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014 We consider the Cauchy problem for the hyperbolic differential equation of the forth order with nonmultiple characteristics. We generalize this problem from the similar Cauchy problem for the hyperbolic differential equation of the third order with ...

Algebraic Linearization of Hyperbolic RuijsenaarsSchneider Systems
Journal of Nonlinear Mathematical Physics, 2001 In this article, we present an explicit linearization of dynamical systems of Ruijsenaars-Schneider (RS) type and of the perturbations introduced by F Calogero [2] of these systems with all orbits periodic of the same period. The existence of this linearization and its algebraic nature relies on the dynamical equation firstly discussed in the article ...

Semigroup estimates and fast-slow dynamics in parabolic-hyperbolic systems
Advances in Nonlinear Analysis, 2018 We present a general procedure to describe slow dynamics in parabolic-hyperbolic systems, under suitable assumptions on the terms appearing in the equations. In particular, our strategy relies in semigroup estimates for the evolution system associated to

Damping problem for the special class of the second order hyperbolic systems
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2012 We consider the damping problem for the hyperbolic system with mixed derivative as the special case of boundary control problem. For different cases the given system is transformed to the triangular or diagonal form, allowing separation of equations.

A survey on well-balanced and asymptotic preserving schemes for hyperbolic models for chemotaxis
ESAIM: Proceedings and Surveys, 2018 Chemotaxis is a biological phenomenon widely studied these last years, at the biological level but also at the mathematical level. Various models have been proposed, from microscopic to macroscopic scales.

Electronic Journal of Differential Equations, 2015 We consider a two-dimensional Riemann problem for the unsteady transonic small disturbance equation resulting in diverging rarefaction waves. We write the problem in self-similar coordinates and we obtain a mixed type (hyperbolic-elliptic) system ...

Deterministic and Stochastic Dynamics in Spinodal Decomposition of a Binary System
Успехи физики металлов, 2009 A model for diffusion and phase separation, which takes into account hyperbolic relaxation of the solute diffusion flux, is developed. Such a ‘hyperbolic model’ provides analysis of ‘hyperbolic evolution’ of patterns in spinodal decomposition in systems ...

A Riemann problem with small viscosity and dispersion
Electronic Journal of Differential Equations, 2006 In this paper we prove existence of global solutions to a hyperbolic system in elastodynamics, with small viscosity and dispersion terms and derive estimates uniform in the viscosity-dispersion parameters.
