Let M be an aftine manifold with a flat affme connection D. A Riemannian metric g on M is said to be a Hessian metric if g has a local expression g = D'u. A manifold M provided with such a pair (D, g) is called a Hessian manifold. We first prove the convexity of a Hessian manifold. We give a Weitzen
The last ten years have seen rapid advances in the understanding of differentiable four-manifolds, not least of which has been the discovery of new 'exotic' manifolds. These results have had far-reaching consequences in geometry, topology, and mathematical physics, and have proven to be a mainspring
