The explicit eigenvalues and eigenfunctions of the generalized neumann kernel in annular domains
(
Universiti Putra Malaysia
, 2019 , Article)
This paper presents the explicit forms of the eigenvalues of the general-ized Neumann kernel in annular domains and the explicit forms of the corresponding eigenfunctions. It follows from these explicit forms that, except ...
