The singular Sturm–Liouville boundary value problem for the equation

It is established completeness of system of eigenfunctions of the corresponding eigenvalue problem, equivalence of a number of statements such as positivity of Green’s function, positive definiteness of a quadratic functional, and others assertions. This is continuation of the work .
