Eigenvalue asymptotics for strong $\hat{I}´$-interactions supported on curves with corners

Badreddine Benhellal, Noah Körner, Konstantin Pankrashkin

Let $\hat{I}“\subset {\mathbb{R}}^2$ be a piecewise smooth closed curve with corners. We discuss the asymptotic behavior of the individual eigenvalues of the two-dimensional Schrödinger op…
