چکیده
|
Warped products provide a rich class of physically signi cant geometric objects. warped product construction is an important method to produce a new metric with a base manifold and a bre. we construct compact base manifolds with a positive scalar curvature which do not admit any non-trivial quasi-einstein warped product, and noncompact complete base manifolds which do not admit any non-trivial ricci- at quasi-einstein warped product.
