초록

In this paper the direct scattering problem with the Sturm-Liouville operator on the half line [0,+∞ is investigated. Some spectral properties are given. The resolvent operator is defined. The expansion formula with respect to eigenfunctions is given and equivalence between this formula and Parseval equality is shown.
