Semiclassical Asymptotics on Manifolds with Boundary

Nilufer Koldan, Igor Prokhorenkov, Mikhail Shubin

We discuss semiclassical asymptotics for the eigenvalues of the Witten Laplacian for compact manifolds with boundary in the presence of a general Riemannian metric. To this end, we…

Discreteness of spectrum and positivity criteria for Schrödinger operators

Vladimir Maz'ya, Mikhail Shubin

We provide a class of necessary and sufficient conditions for the discreteness of spectrum of Schrödinger operators with scalar potentials which are semibounded below. The classica…
