Weakly hyperbolic systems by symmetrization [PDF]

open access: yesANNALI SCUOLA NORMALE SUPERIORE - CLASSE DI SCIENZE, 2019
We study hyperbolic first order systems and propose a new method proving Gevrey well posedness, constructing a symmetrizer, motivated by a special Lyapunov function for linear ODE. The proof not only gives a priori estimates straightforward so simply but also clarifies some effects coming from the spectral structures other than the multiplicities of ...

Solutions to a first order hyperbolic system [PDF]

open access: yesSurveys in Mathematics and its Applications, 2018
The study of small perturbations in the shock initiation of an inviscid compressible fluid with chemical reaction leads to a first order hyperbolic system of two equations.

Uniform stabilization of a coupled structural acoustic system by boundary dissipation

open access: yesAbstract and Applied Analysis, 1998
We consider a coupled PDE system arising in noise reduction problems. In a two dimensional chamber, the acoustic pressure (unwanted noise) is represented by a hyperbolic wave equation.

Open and Dense Topological Transitivity of Extensions by Non-Compact Fiber of Hyperbolic Systems: A Review

open access: yesAxioms, 2015
Currently, there is great renewed interest in proving the topological transitivity of various classes of continuous dynamical systems. Even though this is one of the most basic dynamical properties that can be investigated, the tools used by various ...

Life-Span of Classical Solutions to Hyperbolic Inverse Mean Curvature Flow

open access: yesDiscrete Dynamics in Nature and Society, 2020
In this paper, we investigate the life-span of classical solutions to hyperbolic inverse mean curvature flow. Under the condition that the curve can be expressed in the form of a graph, we derive a hyperbolic Monge–Ampère equation which can be reduced to

N=4 supersymmetric U(2)-spin hyperbolic Calogero-Sutherland model

open access: yesNuclear Physics B, 2020
The N=4 supersymmetric U(2)-spin hyperbolic Calogero-Sutherland model with odd matrix fields is examined. Explicit form of the N=4 supersymmetry generators is derived.

Finite Time Stability of 2D Fractional Hyperbolic System with Time Delay

open access: yesJournal of Function Spaces, 2022
In this work, a class of two-dimensional fractional hyperbolic differential linear system (2D-FHDLS) with time delay is investigated. By using generalized Gronwall’s inequality, sufficient conditions for the finite time stability (FTS) of two-dimensional

Problem for hyperbolic system of equations having constant coefficients with integral conditions with respect to the time variable

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2014
In a domain specified in the form of a Cartesian product of a segment $\left[0,T\right]$ and the space ${\mathbb R}^{p}$, we study a problem with integral conditions with respect to the time variable for  hyperbolic system with constant coefficients in a

Water ow on vegetated hill. 1D shallow water equation type model

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
A mathematical model for the water ow on a hill covered by variable distributed vegetation is proposed in this article. The model takes into account the variation of the geometrical properties of the terrain surface, but it assumes that the surface ...

Quasilinear hyperbolic systems [PDF]

open access: yesCommunications in Mathematical Physics, 1979
We construct global solutions for quasilinear hyperbolic systems and study their asymptotic behaviors. The systems include models of gas flows in a variable area duct and flows with a moving source. Our analysis is based on a numerical scheme which generalizes the Glimm scheme for hyperbolic conservation laws.
