Abstract

In this paper, we consider the cyclic parallel Ricci tensor condition, which is a necessary condition for an affine manifold to be Szab\'o. We show that, in dimension 33, there are affine manifolds which satisfy the cyclic parallel Ricci tensor but are not Szab\'o. Conversely, it is known that in dimension 22, the cyclic parallel Ricci tensor forces the affine manifold to be Szab\'o. Examples of 33-dimensional affine Szabo manifolds are also given. Finally, we give some properties of Riemannian extensions defined on the cotangent bundle over an affine Szab\'o manifold.
