Solvability of Parametric Elliptic Systems with Variable Exponents

open access: yesMoroccan Journal of Pure and Applied Analysis, 2023
In this paper, we study the solvability to the left of the positive infimum of all eigenvalues for some non-resonant quasilinear elliptic problems involving variable exponents.

A Time-Fractional Differential Inequality of Sobolev Type on an Annulus

open access: yesAxioms, 2023
Several phenomena from natural sciences can be described by partial differential equations of Sobolev-type. On the other hand, it was shown that in many cases, the use of fractional derivatives provides a more realistic model than the use of standard ...

Strong solutions for two-dimensional nonlocal Cahn-Hilliard-Navier-Stokes systems [PDF]

open access: yes, 2013
A well-known diffuse interface model for incompressible isothermal mixtures of two immiscible fluids consists of the Navier-Stokes system coupled with a convective Cahn-Hilliard equation.

ASYMMETRIC IMPURITY SEGREGATION IN MULTI-LAYERED FILMS [PDF]

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2013
Peculiarities of segregation of impurities at the boundaries of a thin film separating two different solid materials are considered. Theoretical and numerical analysis of kinetics of impurity redistribution within the film and at the boundaries has been ...

On the uniqueness of weak solution for the 2-D Ericksen--Leslie system

open access: yes, 2016
In this paper, we prove the uniqueness of weak solutions to the two dimensional full Ericksen-Leslie system with the Leslie stress and general Ericksen stress under the physical constrains on the Leslie coefficients. This question remains unknown even in

Two-dimensional incompressible ideal flows in a noncylindrical material domain [PDF]

open access: yes, 2007
The purpose of this work is to prove existence of a weak solution of the two dimensional incompressible Euler equations on a noncylindrical domain consisting of a smooth, bounded, connected and simply connected domain undergoing a prescribed motion.

The asymptotic behavior of solutions to a class of inhomogeneous problems: an Orlicz–Sobolev space approach

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
The asymptotic behavior of the sequence $\{v_n\}$ of nonnegative solutions for a class of inhomogeneous problems settled in Orlicz–Sobolev spaces with prescribed Dirichlet data on the boundary of domain $\Omega$ is analysed.

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.

Regularity of H\"older continuous solutions of the supercritical quasi-geostrophic equation

open access: yes, 2007
We present a regularity result for weak solutions of the 2D quasi-geostrophic equation with supercritical ($\alpha< 1/2$) dissipation $(-\Delta)^\alpha$ : If a Leray-Hopf weak solution is H\"{o}lder continuous $\theta\in C^\delta({\mathbb R}^2)$ with ...
