On some inverse problems as to nodal points of sturm liouville operators with interaction point

In the first chapter of this thesis, Informations about old studies of Differential operators and Sturm-Liouville operatör are given. In the second chapter, Some fundamental definitions and theorems that use of often in Spectral theory of Differential operators are given. In the third chapter, General informations of Sturm-Liouville operators, regular and singular Sturm-Liouville operators, asymptotic formulas for the eigenvalues and eigenfunctions are examined. In the fourth chapter, Inverse nodal problem and new inverse nodal problem are given. In the last chapter, Some inverse problems as to nodal points of sturm liouville operators with interaction point are examined.
