Abstract:
We consider the problem $- \Delta u = \lambda gu$ in ${R^n}$, $u \to 0$ at $\infty$ with $g$ a function that changes sign. Under suitable growth conditions on $g$ we show that this problem has an eigenvalue $\lambda$ with a positive solution $u$, as well as countably many other eigenvalues.References
