Analysis of Schrödinger operators with inverse square potentials {II}: FEM and approximation of eigenfunctions in the periodic case

Eugenie Hunsicker, Hengguang Li, Victor Nistor +1

Let $V$ be a {\em periodic} potential on $\RR^3$ that is smooth everywhere except at a discrete set $\maS$ of points, where it has singularities of the form $Z/{\rho }^2$, with $ρ(x) = |…
