Abstract
We consider the existence of positive solutions to weighted quasilinear elliptic differential equations of the type \[ \begin{cases} - Δ_{p, w} u = σu^{q} & \text{in }, \\ u = 0 & \text{on } \end{cases} \] in the sub-natural growth case , where is a bounded domain in , is a weighted -Laplacian, and is a nonnegative (locally finite) Radon measure on . We give criteria for the existence problem. For the proof, we investigate various properties of -superharmonic functions, especially the solvability of Dirichlet problems with infinite measure data.
