Query: Stability and instability properties of rotating Bose-Einstein
  condensates   We consider the mean-field dynamics of Bose-Einstein condensates in rotating
harmonic traps and establish several stability and instability properties for
the corresponding solution. We particularly emphasize the difference between
the situation in which the trap is symmetric with respect to the rotation axis
and the one where this is not the case.
