Sharp Spectral Asymptotics for Operators with Irregular Coefficients. V.   Multidimensional Schroedinger operator with a strong magnetic field.   Non-Full-rank case
  Sharp spectral asymptotics for multidimensional Schroedinger operators with the strong magnetic field are derived under rather weak smoothness conditions. I assume that magnetic intensity matrix has constant defect r>0 at each point.   In comparison with version 1 of 5.5 year ago this version contains more results (we also study some degenerations), improvements and some minor corrections.
