Existence of positive radial solutions for quasilinear elliptic equations and systems

Electronic Journal of Differential Equations, 2016
Under simple conditions on f and g, we show that existence of positive radial solutions for the quasilinear elliptic equation $$ \hbox{div}(\phi_1(|\nabla u|) \nabla u)=a(|x|)f(u) \quad x\in \mathbb{R}^N, $$ and for the system $$\displaylines{

Multiple solutions for a quasilinear \((p,q)\)-elliptic system

Electronic Journal of Differential Equations, 2013
Summary: We prove the existence of three weak solutions of a quasilinear elliptic system involving a general \((p,q)\)-elliptic operator in divergence form, with ...

EXISTENCES AND BOUNDARY BEHAVIOR OF BOUNDARY BLOW-UP SOLUTIONS TO QUASILINEAR ELLIPTIC SYSTEMS WITH SINGULAR WEIGHTS

, 2014
. Using the method of explosive sub and supper solution, the existence and boundary behavior of positive boundary blow up solutions for some quasilinear elliptic systems with singular weight function are obtained under more extensive conditions.
