Entropy Solution Theory for Fractional Degenerate Convection-Diffusion Equations [PDF]

, 2010
We study a class of degenerate convection diffusion equations with a fractional nonlinear diffusion term. These equations are natural generalizations of anomalous diffusion equations, fractional conservations laws, local convection diffusion equations ...

On weak uniqueness for some degenerate SDEs by global $L^p$ estimates

, 2014
We prove uniqueness in law for possibly degenerate SDEs having a linear part in the drift term. Diffusion coefficients corresponding to non-degenerate directions of the noise are assumed to be continuous.

Energy and momentum relaxation of heavy fermion in dense and warm plasma

, 2010
We determine the drag and the momentum diffusion coefficients of heavy fermion in dense plasma. It is seen that in degenerate matter drag coefficient at the leading order mediated by transverse photon is proportional to $(E-\mu)^2$ while for the ...

Hölder inequality applied on a non-Newtonian fluid equation with a nonlinear convection term and a source term

Journal of Inequalities and Applications, 2018
Consider a non-Newtonian fluid equation with a nonlinear convection term and a source term. The existence of the weak solution is proved by Simon’s compactness theorem.

Regularity Properties of Degenerate Diffusion Equations with Drifts [PDF]

SIAM Journal on Mathematical Analysis, 2017
This paper considers a class of nonlinear, degenerate drift- diffusion equations. We study well-posedness and regularity properties of the solutions, with the goal to achieve uniform H\"{o}lder regularity in terms of $L^p$-bound on the drift vector field.

Principal spectral theory and asymptotic behavior of the spectral bound for partially degenerate nonlocal dispersal systems

Advanced Nonlinear Studies
The purpose of this paper is to investigate the principal spectral theory and asymptotic behavior of the spectral bound for cooperative nonlocal dispersal systems, specifically focusing on the case where partial diffusion coefficients are zero, referred ...

The effective density of randomly moving electrons and related characteristics of materials with degenerate electron gas

AIP Advances, 2014
Interpretation of the conductivity of metals, of superconductors in the normal state and of semiconductors with highly degenerate electron gas remains a significant issue if consideration is based on the classical statistics.
