Resumo: It has long been known that we can use the contact between a surface and so called model submanifolds to tell us about the underlying geometry of the surface. For example, we can tell something about how flat a surface is by its contact with either planes or lines, and something about how round it is by its contact with spheres or circles. In this talk I'll revisit the idea of contact between a surface and circles and introduce the idea of a "surface of centres" of circles with sufficiently high contact, a kind of generalisation to the focal set. This is joint work with Peter Giblin.
