Abstract
The present paper deals with nonreal eigenvalues of singular indefinite Sturm–Liouville boundary value problems with limit-circle type nonoscillation endpoints. An estimate of upper bounds on nonreal eigenvalues for the singular indefinite eigenvalue problems associated to the separated self-adjoint boundary conditions with nonprincipal solutions is obtained.
