Every compact, simply connected, homogeneous kahler manifold admits a unique up to homothety invariant kahlereinstein metric structure this result can be found in y. We also remark that 1quasi einstein manifolds are more commonly called static metrics and such metrics have connections to the prescribed scalar curvature problem, the positive mass theorem and general relativity. To this end, we apply a new technique which is based on a fibration of a flag manifold over another such space and the theory of riemannian submersions.
