Usually, at the heart of a good limit theorem in probability theory is at least one good inequality – because, in applications, a topological neighborhood is usually defined by inequalities. Of course,...

I encountered the following question in my studies: Let us assume we have a real anlaytic solution to an ODE on $\mathbb{R}$ of Schr\"odinger type $-\psi''(x)+V(x)\psi(x)=\lambda \psi(x)$ but we ...
