Strong coupling asymptotics for Schrödinger operators with an interaction supported by an open arc in three dimensions

Pavel Exner, Sylwia Kondej

We consider Schrödinger operators with a strongly attractive singular interaction supported by a finite curve $\Gamma$ of lenghth $L$ in ${\mathbb{R}}^3$. We show that if $\Gamma$ is $C^4$-smooth and…
