Quantum confinement for the curvature Laplacian $-\Delta +cK$ on 2D-almost-Riemannian manifolds

Ivan Beschastnyi, Ugo Boscain, Eugenio Pozzoli

Two-dimension almost-Riemannian structures of step 2 are natural generalizations of the Grushin plane. They are generalized Riemannian structures for which the vectors of a local o…
