Webadmits any Ka¨hler-Einstein metrics. A metric is Ka¨hler-Einstein if it is Ka¨hler and its Ricci curvature form is a constant multiple of its Ka¨hler form. Such a metric provides a special solution of the Einstein equation on Riemannian manifolds. Since the Ricci form represents the ﬁrst Chern class c1–Mƒ, a necessary WebA simple example of a (λ,n+m)-Einstein metric is when w is constant. Then Ric = λg and ∂M = ∅, and we call the space a λ-Einstein manifold. Note that a λ-Einstein manifold is (λ,n+m)-Einstein for all m ≥ 1 and the warped product is a Riemannian product. In this case we say the space is a trivial (λ,n+m)-Einstein manifold.
