Global and non global solutions for a class of coupled parabolic systems

open access: yesAdvances in Nonlinear Analysis, 2020
In the present paper, we investigate the global well-posedness and exponential decay for some coupled non-linear heat equations. Moreover, we discuss the global and non global existence of solutions using the potential well method.

Boundedness and long-time behavior in a parabolic-elliptic system arising from biological transport networks

open access: yesAdvances in Nonlinear Analysis
The aim of this article is to consider a three-dimensional Cauchy problem for the parabolic-elliptic system arising from biological transport networks. For such problem, we first establish the global existence, uniqueness, and uniform boundedness of the ...

Well-posedness of a porous medium flow with fractional pressure in Sobolev spaces

open access: yes, 2016
The nonnegative solution for a linear degenerate diffusion transport eqution is proved. As a result, we show the existence and uniqueness of the solution for the fractional porous medium equation in Sobolev spaces $H^\alpha$ with nonnegative initial data,

The nonlinear diffusion equation of the ideal barotropic gas through a porous medium

open access: yesOpen Mathematics, 2017
The nonlinear diffusion equation of the ideal barotropic gas through a porous medium is considered. If the diffusion coefficient is degenerate on the boundary, then the solutions may be controlled by the initial value completely, the well-posedness of ...

Higher-order anisotropic models in phase separation

open access: yesAdvances in Nonlinear Analysis, 2017
Our aim in this paper is to study higher-order (in space) Allen–Cahn and Cahn–Hilliard models. In particular, we obtain well-posedness results, as well as the existence of the global attractor.
