What is Curvature?, geometry is concerned with properties such as distances, lengths, angles, areas, volumes, and curvature. These concepts, however, are barely mentioned in typical beginning graduate courses in differential geometry; instead, such courses are concerned with smooth structures, flows, tensors, and differential forms.

Definitions and Examples of Riemannian Metrics,we introduce three classes of highly symmetric “model” Riemannian manifolds—Euclidean spaces, spheres, and hyperbolic spaces—to which we will return repeatedly as our understanding deepens and our tools become more sophisticated.

Connections,o define geodesies as curves that minimize length, at least between nearby points. However, this property turns out to be technically difficult to work with as a definition, so instead we’ll choose a different property of straight lines and generalize that.

Peter Vervoort,Ann Pisman,Frédéric Vandermoere,Ilse LootsMM was sited in Australia. The Australian conference theme reflected the country’s cultural heritage, both recent and past – Exchange and Experience in Space and Place. Of the many papers submitted under this theme we were able to identify three core sub-themes: Virtual Heritage, Applied Technologie
