On quasi-linear equation problems involving critical and singular nonlinearities

We consider the singular boundary value problem: { Mathematical Formulas } where Ω ⊂ R^N(N ≥ 3) is a bounded domain such that { Mathematical Formulas }, and h(x) is a given function. Based on different assumptions, using variational methods and Ekeland’s principle, we admit that this problem possesses two positive solutions.
