Positive solutions of nonlinear elliptic equations in a half space in R<sup><small>2</small></sup>

We study the existence and the asymptotic behaviour of positive solutions of the nonlinear equation $Delta u+f(.,u)=0$, in the domain $D={(x_1,x_2)in mathbb{R}^2:x_2>0}$, with $u=0$ on the boundary. The aim is to prove some existence results for the above equation in a general setting by using a...

description We study the existence and the asymptotic behaviour of positive solutions of the nonlinear equation $Delta u+f(.,u)=0$, in the domain $D={(x_1,x_2)in mathbb{R}^2:x_2>0}$, with $u=0$ on the boundary. The aim is to prove some existence results for the above equation in a general setting by using a fixed-point argument.
