STURM-LIOUVILLE PROBLEMS WITH FINITELY MANY POINT δ-INTERACTIONS AND EIGEN-PARAMETER IN BOUNDARY CONDITION.

This paper deals with the Sturm-Liouville equation with a finite number of point δ-interactions and eigenvalue parameter contained in the boundary condition. Sturm-Liouville problem with discontinuities at one or two points and its different variants have already been investigated. In this study we extend these results to a finite number of point δ-interactions case. The crucial part of this study is the using graph demonstration to obtain asymptotic representation of solutions. [ABSTRACT FROM AUTHOR]
