Abstract
We study the optimal value of p for solvability of the problem
Here \(\lambda ,\alpha >0\), \(p>1\), f is a non-negative measurable function and , \(N\geqslant 3\), is an open bounded domain with smooth boundary such that \(0 \in \mathrm{\Omega }\). We find the critical threshold exponent \(p_{+}(\lambda ,\alpha )\) for solvability of (1) and show that if , \(1<p<p_{+}(\lambda ,\alpha )\) and for some sufficiently small \(c_0>0\), then there exists a solution as a limit of solutions to approximating problems. Moreover, for \(p \geqslant p_{+}(\lambda ,\alpha )\) we show that a complete blow-up phenomenon occurs.
