Double phase elliptic inclusions with convection and logarithmic perturbed terms

Bulletin of Mathematical Sciences
This paper deals with a new double phase elliptic inclusion (DPEI) formulated by a double phase partial differential operator with logarithmic perturbation, a general multivalued convection term defined in the domain and a general multivalued term ...

A remark on ground state solutions for Lane-Emden-Fowler equations with a convection term

Electronic Journal of Differential Equations, 2007
Via a sub-supersolution method and a perturbation argument, we study the Lane-Emden-Fowler equation $$ -Delta u =p(x)[g(u)+f(u)+| abla u|^q] $$ in $mathbb{R} ^N$ ($Ngeq3$), where ...

Existence of positive solutions for Kirchhoff type equations

Electronic Journal of Differential Equations, 2013
In this article, we are interested in the existence of positive solutions for the Kirchhoff type problems $$displaylines{ -MBig(int_{Omega}|abla u|^p,dxBig)Delta_pu = lambda f(u) quad hbox{in } Omega,cr u > 0 quad hbox{in } Omega, quad u =0 quad ...

Nonlinear elliptic equations with self-adjoint integro-differential operators and measure data under sign condition on the nonlinearity

Advanced Nonlinear Studies
We study the existence problem for semilinear equations (E): −Au = f(⋅, u) + μ, with Borel measure μ and operator A that generates a symmetric Markov semigroup.
