Some Resolvent Estimates for Sturm Liouv
✍ P. Briet; E. Mourre 📂 Article 📅 1996 🏛 Elsevier Science 🌐 English ⚖ 162 KB

In this paper we derive some a priori estimates on the resolvent of one dimensional Schrodinger operators from the solutions of the associated differential ëquation with real energy. In particular this implies the existence of an absolutely continuous spectrum in some situations.

Some Comparison Theorems for Sturm–Liouv

We give some comparison theorems about the location of the peak of the first Dirichlet Sturm᎐Liouville eigenfunction by means of the variational method.

Gradient Estimates and a Liouville Type

In this paper, we derive a Liouville type theorem on a complete Riemannian manifold without boundary and with nonnegative Ricci curvature for the equation \(\Delta u(x)+h(x) u(x)=0\), where the conditions \(\lim _{r \rightarrow x} r^{-1} \cdot \sup _{x \in B_{p}(r)}|\nabla h(x)|=0\) and \(h \geqslan
