“…While apparently similar in formulation to the nonlocal integral operator commuting with the Laplacian corresponding to the free space Green's function, the Kreȋn-von Neumann problem was shown to be the "farthest", while the anti-periodic problem proved to be the "closest" when seen as finite-rank perturbations. In [30], we will develop the spectral theory of the associate iterated Brownian bridge kernels corresponding to this GSARC framework; see also [13,18,8,9].…”

We reformulate all general real coupled self-adjoint boundary value problems as integral operators and show that they are all finite rank perturbations of the free space Green's function on the real line. This free space Green's function corresponds to the nonlocal boundary value problem proposed earlier by Saito [41]. These are polynomial perturbations of rank up to 4. They encapsulate in a fundamental way the corresponding boundary conditions.
