On Bach flat warped product Einstein manifolds

Differential Geometry 2011-09-16 v2

Abstract

In this paper we show that a compact warped product Einstein manifold with vanishing Bach tensor of dimension n4n \geq 4 is a finite quotient of a warped product with (n1)(n-1)-dimensional Einstein fiber. The fiber has constant curvature if n=4n=4.
