Abstract:
The second and third boundary value problems for the Sturm–Liouville equation in which the weight function is the generalized derivative of a Cantor-type self-similar function are considered. The oscillation properties of the eigenfunctions of these problems are studied, and on the basis of this study, known asymptotics of their spectra are substantially refined. Namely, it is proved that the function $s$ in the well-known formula
$$
N(\lambda)=\lambda^D\cdot [s(\ln\lambda)+o(1)]
$$
decomposes into the product of a decreasing exponential and a nondecreasing purely singular function (and, thereby, is not constant).
Keywords:
Sturm–Liouville problem, self-similar weight, Neumann boundary conditions, third-type boundary conditions, spectral periodicity.
