Bounded weak solutions to nonlinear elliptic equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2009
In this work, we are concerned with a class of elliptic problems with both absorption terms and critical growth in the gradient. We suppose that the data belong to $L^{m}(\Omega)$ with $m>n/2$ and we prove the existence of bounded weak solutions via $L^{\

Global weak solutions to the compressible quantum Navier–Stokes equation and its semi-classical limit [PDF]

open access: yesJournal des Mathématiques Pures et Appliquées, 2016
This paper is dedicated to the construction of global weak solutions to the quantum Navier–Stokes equation, for any initial value with bounded energy and entropy. The construction is uniform with respect to the Planck constant. This allows to perform the

Existence of Weak Solutions to an Evolutionary Model for Magnetoelasticity [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2016
We prove existence of weak solutions to an evolutionary model derived for magnetoelastic materials. The model is phrased in Eulerian coordinates and consists in particular of (i) a Navier-Stokes equation that involves magnetic and elastic terms in the ...

Uniqueness of solutions for a mathematical model for magneto-viscoelastic flows

open access: yes, 2017
We investigate uniqueness of weak solutions for a system of partial differential equations capturing behavior of magnetoelastic materials. This system couples the Navier-Stokes equations with evolutionary equations for the deformation gradient and for ...

Modeling and analysis of a phase field system for damage and phase separation processes in solids [PDF]

open access: yes, 2013
In this work, we analytically investigate a multi-component system for describing phase separation and damage processes in solids. The model consists of a parabolic diffusion equation of fourth order for the concentration coupled with an elliptic system ...

Weak solutions with unbounded variation [PDF]

open access: yesProceedings of the American Mathematical Society, 1973
To solve a quasilinear system of hyperbolic partial differential equations with given initial data, the usual procedure is to approximate the initial data, solve the resulting problems, and show that the variation of the approximating solutions is uniformly bounded. A limiting process then can be used.
