On existence of the resolvent and discreteness of the spectrum of a class of differential operators of hyperbolic type

On existence of the resolvent and discreteness of the spectrum of a class of differential operators of hyperbolic type

The existence and compactness of the resolvent are studied in this paper. One of the main results is the criterion of discreteness of the spectrum of a hyperbolic singular differential operator.
