On the characterization of Riemannian warped product Einstein metrics

We present a series of results, including local characterizations of $(λ,m+n)$-Einstein metrics in the context of warped product Einstein spaces. Using these local properties, we restate already known global characterizations of $(λ,m+n)$-Einstein manifolds from He, Petersen and Wylie.
