Proof of the Basic Invariant Imbedding Method for Fredholm Integral Equations with Displacement Kernels--I.
A validation for the invariant imbedding method for the case of a Fredholm integral equation in which the forcing term is an exponential function. Application of the invariant imbedding approach has resulted in various transformations for converting integral equations, two-point boundary-value problems, and variational problems into easily computed Cauchy problems. To consolidate these analytic and computational gains and improve understanding of the associated Cauchy problems, this Memorandum proves, conversely, that the solution of the Cauchy problem satisfies the original functional equation. RM-6038, a companion study, completes the validation by offering a proof for the case of a general forcing term g. 30 pp. Refs. (KB)
