oblique derivative; elliptic problem; indefinite weight; eigenvalues; principal vectors
Summary:
In this paper we derive results concerning the angular distrubition of the eigenvalues and the completeness of the principal vectors in certain function spaces for an oblique derivative problem involving an indefinite weight function for a second order elliptic operator defined in a bounded region.
