  For example, if the tangent bundle of a Kähler manifold is trivial, then it is already a torus, i.e., the triviality of the tangent bundle already implies global flatness. 
  We investigate the geometry of coverings of algebraic varieties which is to a large extent determined by a certain vector bundle on the base of the covering.
