On Similarity of Indefinite Sturm-Liouville Operators
Abstract
In this note we give sufficient conditions for the coefficients of a singular Sturm-Liouville operator on ℝ with an indefinite weight function such that the operator is similar to a self-adjoint operator in the Hilbert space L2(ℝ). (© 2012 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim)
