Query: K\"ahler geometry on complex projective spaces via reduction and
  unfolding   We review how a reduction procedure along a principal fibration and an
unfolding procedure associated to a suitable momentum map allow to describe the
K\"ahler geometry of a finite dimensional complex projective spaces.
