    and its adjoint system are written as Stielties integral equation systems with end
point boundary conditions. Fundamental matrices are exhibited and, from
these, a spectral analysis and a Green’s matrix are produced. These are
used to achieve spectral resolutions in both self-adjoint and nonself-adjoint
situations. |
