Instabilities and propagation of neutrino magnetohydrodynamic waves in arbitrary direction [PDF]
, 2017 In a previous work [16], a new model was introduced, taking into account the role of the Fermi weak force due to neutrinos coupled to magnetohydrodynamic plasmas. The resulting neutrino-magnetohydrodynamics was investigated in a particular geometry associated with the magnetosonic wave, where the ambient magnetic field and the wavevector are ...

Low Mach Number Limit of Viscous Compressible Magnetohydrodynamic Flows [PDF]
arXiv, 2009 The relationship between the compressible magnetohydrodynamic flows with low Mach number and the incompressible magnetohydrodynamic flows is investigated. More precisely, the convergence of weak solutions of the compressible isentropic viscous magnetohydrodynamic equations to the weak solutions of the incompressible viscous magnetohydrodynamic ...

Instability of the magnetohydrodynamics system at vanishing Rm [PDF]
, 2012 The aim of this note is to study the dynamo properties of the magnetohydrodynamics system at vanishing Rm. Improving the analysis of a former study, we shall establish a generic Lyapunov instability result.

Existence of weak solutions to the three-dimensional density-dependent generalized incompressible magnetohydrodynamic flows [PDF]
arXiv, 2011 In this paper we consider the equations of the unsteady viscous, incompressible, and heat conducting magnetohydrodynamic flows in a bounded three-dimensional domain with Lipschitz boundary. By an approximation scheme and a weak convergence method, the existence of a weak solution to the three-dimensional density dependent generalized incompressible ...

On some large global solutions for the compressible magnetohydrodynamic system [PDF]
arXiv, 2018 In this paper we consider the global well-posedness of compressible magnetohydrodynamic system in $\R^d$ with $d\geq2$, in the framework of the critical Besov spaces. We can show that if the initial data, the shear viscosity and the magnetic diffusion coefficient are small comparing with the volume viscosity, then compressible magnetohydrodynamic ...
