Abstract
In this article we give three characterizations of real self-adjoint operators associated with the singular Sturm–Liouville expressions (Formula presented.) The first characterization is based on the construction of extensions of the domain of the minimal operator associated with ℓ, the second is based on the behavior of certain functions in their domain near the endpoints and the third is based on the boundary conditions satisfied by such extensions.
