A Bound for the Eigenvalue Counting Function for Higher-Order Krein Laplacians on Open Sets

Fritz Gesztesy, Ari Laptev, Marius Mitrea +1

For an arbitrary nonempty, open set $\Omega \subset {\mathbb{R}}^n$, $n\in \mathbb{N}$, of finite (Euclidean) volume, we consider the minimally defined higher-order Laplacian $(- Δ)^m\big…
