Abstract:
This paper presents the explicit forms of the eigenvalues of the generalized Neumann kernel in annular domains and the explicit forms of the corresponding eigenfunctions. It follows from these explicit forms that, except for -1, the eigenvalues are in the unit disk and clustered around 0.

Keywords: Generalized Neumann kernel, eigenvalues, eigenfunctions, Fourier series.
