A complex flag manifold is a quotient of a complex semisimple Lie group by a parabolic subgroup (a subgroup which contains a Borel subgroup). Basic examples are complex projective space and the complex Grassmannians. Now all complex Grassmannian spaces are symmetric spaces, my question is: Which complex flag manifolds are symmetric?
