Regularity for 3-D MHD Equations in Lorentz Space $L^{3,∞}$
The regularity for 3-D MHD equations is considered in this paper, it is proved that the solutions (v,B,p) are Hölder continuous if the velocity field v∈L∞(0,T;L x (R 3)) with local small condition r ∣∣ { x∈Br(x0) : |v(x,t0)|> εr −1 ∣∣≤ ε and the magnetic

Stratified Radiative Transfer in a Fluid and Numerical Applications to Earth Science
New mathematical results are given for the Radiative Transfer equations alone and coupled with the temperature equation of a fluid: existence, uniqueness, a maximum principle and a convergent monotone iterative scheme.

Zero Viscosity-Diffusivity Limit for the Incompressible Boussinesq Equations in Gevrey Class
In this paper, we study the zero viscosity-diffusivity limit for the incompressible Boussinesq equations in a periodic domain in the framework of Gevrey class. We first prove that there exists an interval of time, independent of the viscosity coefficient

Stability estimate for the semi-discrete linearized Benjamin-Bona-Mahony equation
In this work we study the semi-discrete linearized Benjamin-Bona-Mahony equation (BBM) which is a model for propagation of one-dimensional, unidirectional, small amplitude long waves in non-linear dispersive media.

On the statistical properties of the 3D incompressible Navier-Stokes-Voigt model [PDF]
The Navier-Stokes-Voigt (NSV) model of viscoelastic incompressible fluid has been recently proposed as a regularization of the 3D NavierStokes equations for the purpose of direct numerical simulations.

Mathematical Modeling and Simulation of Antibubble Dynamics
In this study, we propose a mathematical model and perform numerical simulations for the antibubble dynamics. An antibubble is a droplet of liquid surrounded by a thin film of a lighter liquid, which is also in a heavier surrounding fluid.

Global well-posedness for the critical 2D dissipative quasi-geostrophic equation [PDF]
We give an elementary proof of the global well-posedness for the critical 2D dissipative quasi-geostrophic equation. The argument is based on a non-local maximum principle involving appropriate moduli of continuity.Comment: 7 ...
