Plane Stagnation Double-Diffusive MHD Convective Flow with Convective Boundary Condition in a Porous Media
Plane Stagnation Double-Diffusive MHD Convective Flow and Porous Media
2013/1/30
A numerical analysis has been carried out to study the problem of plane stagnation double-diffusive MHD convective flow with convective boundary condition in a porous media. The governing nonlinear pa...
We define a new diffusive matrix model converging towards the $\beta$-Dyson Brownian motion for all $\beta\in [0,2]$ that provides an explicit construction of $\beta$-ensembles of random matrices that...
The frequency-dependent Wright-Fisher model: diffusive and non-diffusive approximations
frequency-dependent Wright-Fisher model non-diffusive approximations Analysis of PDEs
2011/9/30
Abstract: We study a class of processes that are akin to the Wright-Fisher model, with transition probabilities weighted in terms of the frequency-dependent fitness of the population types. Following ...
Well posedness of an isothermal diffusive model for binary mixtures of incompressible fluids
Diffuse interface model Cahn-Hilliard-Navier-Stokes equations

Q-conditional symmetries of the classical Lotka-Volterra system in the case of one space variable are completely described and a set of such symmetries in explicit form is constructed. The relevant no...
We consider a liquid bearing gas bubbles. When gas bubbles are immovably trapped in a porous matrix by surface tension forces, the dominant mechanism of transfer of gas mass becomes the diffusion of g...
