Existence of solutions for an elliptic equation with indefinite weight

Nonlinear Analysis: Theory, Methods & Applications, 2007
The authors deal with the existence of solutions of the following elliptic equation: \[ -\Delta_x u= V(x)u+ f(x,u),\quad u\in H^1(\mathbb{R}^N),\tag{1} \] where \(V(x)\) is a function with possibly changing sign, \(f\) is a continuous function on \(\mathbb{R}^N\times \mathbb{R}\).

Sturm–Liouville problems with indefinite weights and Everitt's inequality

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1996
It is shown that spectral properties of Sturm–Liouville eigenvalue problems with indefinite weights are related to integral inequalities studied by Everitt. A result of Beals on indefinite problems leads to a sufficient condition for the validity of such an inequality.
