Poincare constant on non-convex domain
I'm wondering if there is any results on the optimal constant for the Poincare inequality on a non-convex domain in $\mathbb{R}^3$, since most of the things I found are results on convex ones.
Any r …

Potential scattering for non-decaying potential
I am reading this note on potential scattering by Siu-Hung Tang and Maciej Zworski.
Just wondering if there is a scattering theory for the Schrödinger with a non-decaying potential $- \Delta + V$ on t …

Lower bound of the spectrum of a Schrodinger operator on a bounded domain
I am trying to look for references on estimate of the lower bound of the spectrum of a Schrodinger operator $-\Delta + V$ on a bounded domain in three-dimensional space. For simplicity, we can take th …
