Global Solution to the Three-Dimensional Compressible Flow of Liquid Crystals [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2013
The Cauchy problem for the three-dimensional compressible flow of nematic liquid crystals is considered. Existence and uniqueness of the global strong solution are established in critical Besov spaces provided that the initial datum is close to an ...

Incompressible limit for compressible viscoelastic flows with large velocity

open access: yesAdvances in Nonlinear Analysis, 2023
We are concerned with the incompressible limit of global-in-time strong solutions with arbitrary large initial velocity for the three-dimensional compressible viscoelastic equations.

Modelling and analysis of fractal-fractional partial differential equations: Application to reaction-diffusion model

open access: yesAlexandria Engineering Journal, 2020
In this paper, an extension is paid to an idea of fractal and fractional derivatives which has been applied to a number of ordinary differential equations to model a system of partial differential equations.

On the harmonic Boltzmannian waves in laser-plasma interaction [PDF]

open access: yes, 2006
We study the permanent regimes of the reduced Vlasov-Maxwell system for laser-plasma interaction. A non-relativistic and two different relativistic models are investigated.

Exact Boundary Conditions at an Artificial Boundary for Partial Differential Equations in Cylinders [PDF]

open access: yes, 1986
The numerical solution of partial differential equations in unbounded domains requires a finite computational domain. Often one obtains a finite domain by introducing an artificial boundary and imposing boundary conditions there. This paper derives exact

Existence of weak solutions for general nonlocal and nonlinear second-order parabolic equations [PDF]

open access: yes, 2008
In this article, we provide existence results for a general class of nonlocal and nonlinear second-order parabolic equations. The main motivation comes from front propagation theory in the cases when the normal velocity depends on the moving front in a ...

Analytical results for 2-D non-rectilinear waveguides based on the Green's function [PDF]

open access: yes, 2007
We consider the problem of wave propagation for a 2-D rectilinear optical waveguide which presents some perturbation. We construct a mathematical framework to study such a problem and prove the existence of a solution for the case of small imperfections.

open access: yes, 1998
Classificação AMS: 76P05, 35A05, 35L50In this paper an initial-boundary value problem in one space dimension is studied for the Broadwell model extended to a gas mixture undergoing to bimolecular reactions.

Asymptotic behaviour of reversible chemical reaction-diffusion equations [PDF]

open access: yes, 2010
We investigate the asymptotic behavior of the a large class of reversible chemical reaction-diffusion equations with the same diffusion. In particular we prove the optimal rate in two cases : when there is no diffusion and in the classical "two-by-two ...

A vanishing diffusion limit in a nonstandard system of phase field equations [PDF]

open access: yes, 2012
We are concerned with a nonstandard phase field model of Cahn-Hilliard type. The model, which was introduced by Podio-Guidugli (Ric. Mat. 2006), describes two-species phase segregation and consists of a system of two highly nonlinearly coupled PDEs.
