We consider the uniform attractors of a 3D non-autonomous Brinkman-Forchheimer equation with a singularly oscillating force∂u/∂t-γΔu+au+b|u|u+c|u|^(2)u+∇p=f_(0)(x,t)+ε^(-ρ)f_( 1)(x,t/ε),for ρ∈[0,1)and ε>0,and ...

We investigate the Kirchhoff type elliptic problem(a+b∫_(R^(N))[|∇u|^(2)+V(x)u^(2)]dx)[-Δu+V(x)u]=f(x,u),x∈R^(N),where both V and f are periodic in x,0 belongs to a spectral gap of−∆+V.Under suitable assumptions on...

Let Ω be a smooth bounded domian in R^(2),H_(0)^(1)(Ω)be the standard Sobolev space,and λ_(f)(Ω)be the first weighted eigenvalue of the Laplacian,namely,λ_(f)(Ω)=inf_(u∈H_(0)^(1)(Ω),∫Ωu^(2)dx=1)∫_(Ω)|∇u|^(...
This paper is devoted to establishing the Adams-Onofri inequality with logarithmic weight for the second order radial Sobolev space defined on the unit ball in IR4.By using this inequality we obtain the existence of s...

This artical concerns the C_(loc)^(1,α)-regularity of weak solutions u to the degenerate subelliptic p-Laplacian equationΔ_(H,p)u(x)=∑_(i=1)^(6)X_(i)^(*)(|∇_(H)u|^(p-2)X_(i)u)=0,where H is the orthogonal complement...
This work considers the initial boundary value problem for a viscoelastic wave equation with a nonlinear boundary source term.Under suitable assumptions,we prove the existence of global weak solutions using the Galerk...

In this paper we firstly prove the global well-posedness for the compressible Hall-magnetohydrodynamic system in a bounded domain when the initial data is small.On this basis,we continue to study the convergence of th...

Motivated by a recent work of Wang-Yang[19],we study the compactness of extremals[ug]for singular Hardy-Trudinger-Moser inequalities due to Hou[24].In particular,by the method of blow-up analysis,we conclude that,up t...
This paper presents a method of lines solution based on the reproducing kernel Hilbert space method to the nonlinear one-dimensional Klein-Gordon equation that arises in many scientific fields areas.Our method uses di...
