Euler-α equations in a three-dimensional bounded domain with Dirichlet boundary conditions

open access: yesOpen Mathematics
In this article, we investigate the Euler-α\alpha equations in a three-dimensional bounded domain. On the one hand, we prove in the Euler setting that the equations are locally well-posed with initial data in Hs(s≥3){H}^{s}\left(s\ge 3).

Global in time well-posedness of a three-dimensional periodic regularized Boussinesq system

open access: yesDemonstratio Mathematica
Global in time weak solution to a regularized periodic three-dimensional Boussinesq system is proved to exist in energy spaces. This solution depends continuously on the initial data. In particular, it is unique.

Existence results for nonhomogeneous Choquard equation involving p-biharmonic operator and critical growth

open access: yesDemonstratio Mathematica
In this article, we are interested in the existence of nontrivial solutions for the following nonhomogeneous Choquard equation involving the pp-biharmonic operator: M∫Ω∣Δu∣pdxΔp2u−Δpu=λ(∣x∣−μ⁎∣u∣q)∣u∣q−2u+∣u∣p*−2u+f,inΩ,u=Δu=0,on∂Ω,\left\{\begin{array}{l}

Analysis of weak solutions of a phase-field model for sea ice evolution

open access: yesAlexandria Engineering Journal, 2023
This paper is devoted to the study of the well-posedness of an initial-boundary value problem (IVBP) for a three-dimensional two-phase system, which is a phase-field model consisting of two coupled parabolic equations and is used to describe the solid ...

Infinitely many solutions for Hamiltonian system with critical growth

open access: yesAdvances in Nonlinear Analysis
In this article, we consider the following elliptic system of Hamiltonian-type on a bounded domain:−Δu=K1(∣y∣)∣v∣p−1v,inB1(0),−Δv=K2(∣y∣)∣u∣q−1u,inB1(0),u=v=0on∂B1(0),\left\{\begin{array}{ll}-\Delta u={K}_{1}\left(| y| ){| v| }^{p-1}v,\hspace{1.0em ...

Moving planes and sliding methods for fractional elliptic and parabolic equations

open access: yesAdvanced Nonlinear Studies
In this paper, we summarize some of the recent developments in the area of fractional elliptic and parabolic equations with focus on how to apply the sliding method and the method of moving planes to obtain qualitative properties of solutions.
