Problems pertaining to the nonrelativistic diagram technique are considered. Assuming constant vertices, a representation of an arbitrary diagram is obtained in the form of an integral over Feynman parameters. The analytic properties of the diagrams as functions of kinematic invariants are discussed. Real singularities of singlecontour diagrams are considered, and an explicit expression of the amplitude for a triangular diagram is derived. (auth)
