Finite Time Stabilization of Nonautonomous First-Order Hyperbolic Systems [PDF]

open access: yesSIAM Journal on Control and Optimization, 2021
We address nonautonomous initial boundary value problems for decoupled linear first-order one-dimensional hyperbolic systems, investigating the phenomenon of finite time stabilization. We establish sufficient and necessary conditions ensuring that solutions stabilize to zero in a finite time for any initial $L^2$-data. In the nonautonomous case we give

Analytic critical points of charged Rényi entropies from hyperbolic black holes

open access: yesJournal of High Energy Physics, 2021
We analytically study phase transitions of holographic charged Rényi entropies in two gravitational systems dual to the N $$ \mathcal{N} $$ = 4 super-Yang-Mills theory at finite density and zero temperature.

On the Limitations of Physics-Informed Deep Learning: Illustrations Using First-Order Hyperbolic Conservation Law-Based Traffic Flow Models

open access: yesIEEE Open Journal of Intelligent Transportation Systems, 2023
Since its introduction in 2017, physics-informed deep learning (PIDL) has garnered growing popularity in understanding the systems governed by physical laws in terms of partial differential equations (PDEs).

Leaderless Consensus of Semilinear Hyperbolic Multiagent Systems with Semipositive or Seminegative Definite Convection

open access: yesDiscrete Dynamics in Nature and Society, 2022
This paper deals with a leaderless consensus of semilinear first-order hyperbolic partial differential equation-based multiagent systems (HPDEMASs). A consensus controller under an undirected graph is designed.

Multi-Parameter Reaction–Diffusion Systems with Quadratic Nonlinearity and Delays: New Exact Solutions in Elementary Functions

open access: yesMathematics, 2022
The study considers a nonlinear multi-parameter reaction–diffusion system of two Lotka–Volterra-type equations with several delays. It treats both cases of different diffusion coefficients and identical diffusion coefficients.

Numerical solution of compressible Euler and Magnetohydrodynamic flow past an infinite cone

open access: yesApplications in Engineering Science, 2021
A numerical scheme is developed for systems of conservation laws on manifolds which arise in high speed aerodynamics and magneto-aerodynamics. The systems are presented in an arbitrary coordinate system on the manifold and involve source terms which ...
