Criteria of discreteness of spectrum and strict positivity for magnetic Schr\"odinger operatorsMathematical Physics & Probability
|Speaker: ||Prof. Mikhail Shubin, Northeastern University|
|Location: ||693 Kerr|
|Start time: ||Tue, May 1 2001, 4:10PM|
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.
