Positive solutions to the weighted critical quasilinear problems

In a bounded domain with smooth boundary, we consider a kind of weighted quasilinear elliptic problem, which satisfies Dirichlet boundary condition and involves the Hardy-Sobolev inequality. By the analytic techniques, we first get the properties of the extremal functions by which the best Hardy-Sobolev constant is achieved. Then by the variational methods, the existence of positive solutions to the problem is verified by careful estimates and computations.
