Title: Weak solutions for degenerate semilinear elliptic BVPs in
unbounded domains
Author: Rasmita Kar (Indian Inst. of Technology, Kanpur, India)
Abstract:
In this article, we prove the existence of a weak solution for the
degenerate semilinear elliptic Dirichlet boundary-value problem
$$\displaylines{
Lu(x)+\sum_{i=1}^n g(x)h(u(x))D_iu(x)=f(x)\quad \hbox{in }\Omega,\cr
u=0\quad \hbox{on }\partial\Omega,
}$$
in a suitable weighted Sobolev space. Here
$\Omega\subset\mathbb{R}^n$, $1\leq n\leq3,$ is not necessarily bounded.
