For a simply connected nilpotent Lie group L, we construct a complete
metric with positive Ricci curvature on the product manifold L \Theta R p , where
p is taken sufficiently large. The construction uses a warped product method
and involves subtle choices of functions. We endow L with a family of al­
most flat metrics, and the little ``negativeness'' of L can be compensated by
warping the euclidean R p factor. From the construction one also sees that
the isometry group of the resulting manifold contains the original group L.

A basic consequence of this construction is that every finitely generated
