We consider the existence of positive solutions of the equation
$1/λ(t) (λ(t)φ_p(x'(t)))' + μf(t,x(t),x'(t)) =0$,
where $φ_p(s) = |s|^{p-2}s$, p > 1, subject to some singular Sturm-Liouville boundary conditions. Using the Krasnosel'skiĭ fixed point theorem for operators on cones, we prove the existence of positive solutions under some structure conditions.
