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.
