Spectral analysis of Hahn-Dirac system
Keywords:Hahn-Dirac system, Self-adjoint operator, Eigenvalues and eigenfunctions, Green’s matrix, Eigenfunction expansion
In this paper, we study some spectral properties of the one-dimensional Hahn-Dirac boundary-value problem, such as formally self-adjointness, the case that the eigenvalues are real, orthogonality of eigenfunctions, Greens function, the existence of a countable sequence of eigenvalues, eigenfunctions forming an orthonormal basis of L2w,q ((w0. a): E).
