Delstarte transform operators: the topological
structure and applications
The structure of Delsarte transform operators, generalizing Faddeev-Nizhnik integral representation
of Volterra type for multi- dimensional differential operators is studied by means of
differential-geometric and topological methods. An extension of the method for the case of affine
pencils of differential operators is suggested. Application to spectral theory are discussed.
