Construction of an A-manifold on a principal torus bundle

By Grzegorz Zborowski


We construct a new example of an A-manifold, i.e. a Riemannian manifold with a cyclic-parallel Ricci tensor, which can be viewed as a generalization of the Einstein condition. The underlying manifold for our construction is a principal torus bundle over K\"ahler-Einstein manifold a with fibre a torus of arbitrary dimension
