Abstract: We provide existence, uniqueness and regularity results of a degenerate singular elliptic boundary value problem whose model is given by
\({div}\)\((w(x)\nabla u^{p2}\nabla u)\)=\(\frac{f}{u^\delta}\,\,\text{ in }\,\,\Omega,\)
\(u>0\text{ in }\Omega,\\ u = 0 \text{ on } \partial\Omega,\)
where \(\Omega\) is a bounded smooth domain in \(\mathbb{R}^N\) with \(N\geq 2\), \(w\) belong to the Muckenhoupt class \(A_p\) for some \(1<p<\infty\), \(f\) is a nonnegative function belong to some Lebesgue space and \(\delta>0\). The main tools are weighted Sobolev space, embedding theorems and a priori estimates.
