Equiconvergence with Fourier Series for Non-Classical Sturm-Liouville Problems

Year 2019, Volume: 11 Issue: 2, 107 - 111, 31.12.2019

Abstract

Sturm-Liouville type boundary-value problems arise in many engineering and scientific disciplines as the mathematical modeling of systems and processes in the fields of chemistry, aerodynamics, electrodynamics of complex medium or polymer rheology. For example the vibration of a homogeneous loaded strings, the earth's free oscillations,  the interaction of atomic particles, sound, surface waves, heat transfer in a rod with heat capacity concentrated at the ends, electromagnetic waves and gravitational waves can be solved using the Sturmian theory. A large class of physical problems require the investigation of the Sturm-Liouville type problems with discontinuities. Examples are vibration problems under various loads such as a vibrating string with a tip mass or heat conduction through a liquid solid interface.
In this study we shall investigate some properties of the eigenfunctions of one discontinuous Sturm-Liouville Problem. We shall prove some preliminary results related to the basic solutionsGreen's function, resolvent operator and selfadjointness of the considered problem. Particularly we shall present a new approach for constructing the Green's function which is not standard one generally found in textbooks. The obtained results are implemented to the investigation of the basis properties of the system of eigenfunctions in modified Hilbert spaces. Finally, we shall show that the eigenfunction expansion series regarding the convergence behaves in the same way as an ordinary Fourier series.
