Flow Through Randomly Curved Manifolds
We present a computational study of the transport properties of campylotic (intrinsically curved) media. It is found that the relation between the flow through a campylotic media, consisting of randomly located curvature perturbations, and the average Ricci scalar of the system, exhibits two distinct functional expressions, depending on whether the typical spatial extent of the curvature pertur...

متن کاملQuantization on Curved Manifolds
Since the early days of quantum mechanics many techniques have been developed in order to deal with manifolds with non-trivial topology. Among them two techniques have received a great attention in the literature and are shortly reviewed here as they are most geometrical in nature. These are the Kostant–Souriau geometric quantization scheme and the so called constrained quantum mechanics. A not...
متن کاملNegatively Ricci Curved Manifolds
In this paper we announce the following result: “Every manifold of dimension ≥ 3 admits a complete negatively Ricci curved metric.” Furthermore we describe some sharper results and sketch proofs.
متن کاملDiffeomorphisms of Curved Manifolds
We obtain an expression for the curvature of the Lie group SDiffM and use it to derive Lukatskii's formula for the case where M is locally Euclidean. We discuss qualitatively some previous findings for SDiffS 2 in conjunction with our result.
