We characterize the principal eigenvalue associated to the singular quasilinear elliptic operator

in a bounded smooth domain Ω ⊂ RN with zero Dirichlet boundary conditions. Here,
1 < q ≤ 2 and 0 ≤ µ ∈ L∞(Ω). As applications we derive some existence of solutions results (as well as
uniqueness, nonexistence and homogenization results) to a problem whose model is
−∆u = λu + µ(x)
