Abstract
We investigate elliptic equations related to the Caffarelli–Kohn–Nirenberg inequalities: \({-div(|x|^\alpha |\nabla u|^{p-2}\nabla u)=|x|^\beta u^{p(\alpha,\beta)-1}, u(x) > 0,\,x\in\Omega\subset\mathbb{R}^N} (N\geq 3), 1<p<N\) and \({\alpha, \beta\in \mathbb{R}}\) such that \({\frac{p(N+\beta)}{N-p+\alpha} > p}\) . For various parameters α, β and various domains Ω, we establish some existence and non-existence results of solutions in rather general, possibly degenerate or singular settings.
