## Spectral properties of the second order difference equation with selfadjoint operator coefficients

#### Gökhan MUTLU [1]

In this paper, we consider the second order difference equation defined on the whole axis with selfadjoint operator coefficients. The main objective of this study is to obtain the continuous and discrete spectrum of the discrete operator which is generated by this difference equation. To achieve this, we first obtain the Jost solutions of this equation explicitly and then examine the analytical and asymptotic properties of these solutions. With the help of these properties we find the continuous and discrete spectrum of this operator. Finally we obtain the sufficient condition which ensures that this operator has a finite number of eigenvalues.
