An eigenvalue problem involving a degenerate and singular elliptic operator
Mihai Mihăilescu, Dusan D. Repovs · Project Euclid (Cornell University) · 2011
We study an eigenvalue problem involving a degenerate and singular elliptic operator on the whole space $\\mathbb R^N$. We prove the existence of an unbounded and increasing sequence of eigenvalues. Our study generalizes to the case of degenerate and singular operators a result of A. Szulkin and M. Willem.
