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.

WebAug 16, 2024 · I understand that a Kaehler manifold $(M, \omega)$ (or any Riemannian manifold) has constant scalar curvature if it is Einstein. The opposite is not true: it is possible to have a constant scalar curvature Kaehler metric which is not Einstein. I just can't think of any examples. Can you give me one? I think it would be useful for others too.
