Accurate semiclassical spectral asymptotics for a two-dimensional magnetic Schrödinger operator
Bernard Helffer, Yuri A. Kordyukov
We revisit the problem of semiclassical spectral asymptotics for a pure magnetic Schrödinger operator on a two-dimensional Riemannian manifold. We suppose that the minimal value $b…

Semiclassical spectral asymptotics for a magnetic Schrödinger operator with non-vanishing magnetic field
Bernard Helffer, Yuri A. Kordyukov
We consider a magnetic Schrödinger operator , depending on a semiclassical parameter , on a compact Riemannian manifold. We assume that there is no electric field. We sup…

Riemannian foliations of bounded geometry
Jesús A. Álvarez López, Yuri A. Kordyukov, Eric Leichtnam
Continuing the study of bounded geometry for Riemannian foliations, begun by Sanguiao, we introduce a chart-free definition of this concept. Our main theorem states that it is equi…
