Existence and asymptotic behavior of solutions to the generalized damped Boussinesq equation

Electronic Journal of Differential Equations, 2012
We consider the Cauchy problem for the n-dimensional generalized damped Boussinesq equation. Based on decay estimates of solutions to the corresponding linear equation, we define a solution space with time weighted norms.

Weak solutions for degenerate semilinear elliptic BVPs in unbounded domains

Electronic Journal of Differential Equations, 2012
In this article, we prove the existence of a weak solution for the degenerate semilinear elliptic Dirichlet boundary-value problem $$displaylines{ Lu(x)+sum_{i=1}^n g(x)h(u(x))D_iu(x)=f(x)quad hbox{in }Omega,cr u=0quad hbox{on }partialOmega, }$$ in

Local W^{1,p}-regularity estimates for weak solutions of parabolic equations with singular divergence-free drifts

Electronic Journal of Differential Equations, 2017
We study weighted Sobolev regularity of weak solutions of non-homogeneous parabolic equations with singular divergence-free drifts. Assuming that the drifts satisfy some mild regularity conditions, we establish local weighted $L^p$-estimates for the

Existence of weak solutions for degenerate semilinear elliptic equations in unbounded domains

Electronic Journal of Differential Equations, 2009
In this study, we prove the existence of a weak solution for the degenerate semilinear elliptic Dirichlet boundary-value problem $$displaylines{ Lu-mu u g_{1} + h(u) g_{2}= fquad hbox{in }Omega,cr u = 0quad hbox{on }partialOmega }$$ in a suitable ...

Ground states for a modified capillary surface equation in weighted Orlicz-Sobolev space

Electronic Journal of Differential Equations, 2015
In this article, we prove a compact embedding theorem for the weighted Orlicz-Sobolev space of radially symmetric functions. Using the embedding theorem and critical points theory, we prove the existence of multiple radial solutions and radial ground ...
