Criteria of discreteness of spectrum and strict positivity for magnetic Schr\"odinger operators
Probability| Speaker: | Prof. Mikhail Shubin, Northeastern University |

Conditions of discreteness of spectrum and strict positivity for magnetic Schr\"odinger operators with non-negative electric potentials will be discussed. They are formulated in terms of Wiener capacity and effective potentials which combine electric and magnetic fields.
