BOUNDS ON VOLUME GROWTH OF GEODESIC BALLS FOR EINSTEIN WARPED PRODUCTS.

The purpose of this note is to provide some volume estimates for Einstein warped products similar to a classical result due to Calabi and Yau for complete Riemannian manifolds with nonnegative Ricci curvature. To do so, we make use of the approach of quasi-Einstein manifolds which is directly related to Einstein warped products. In particular, we present an obstruction for the existence of such a class of manifolds. [ABSTRACT FROM AUTHOR]
