Let us consider the boundary value problem (BVP) for the discrete Sturm-Liouville equation where (a n ) and (b n ), n β N are complex sequences, Ξ³ i , Ξ² i β C, i = 0, 1, and Ξ» is a eigenparameter. Discussing the point spectrum, we prove that the BVP (0.1), (0.2) has a finite number of eigenvalues a
