Title: What Is Curvature?
Abstract:
A plane curve has a curvature: it measures how fast the tangent turns. For a surface sitting in space, the natural analogue is the product of the two principal curvatures. But this is a definition made from the outside, by someone looking at the surface. Could a creature living on the surface — with no access to the surrounding space, able only to measure distances and areas within its own world — discover that it is curved?
It can, and there is more than one way. Draw a disk of radius r and measure its area: it will not be πr², and the error knows the curvature. Or carry a stick around a small, closed loop, keeping it as straight as you can the whole way, and see where it points when you return. Neither experiment requires leaving the surface.
That these two experiments agree is not a coincidence, and following the coincidence leads somewhere unexpected: the total curvature of a closed surface cannot be chosen freely. It is fixed by the topology. A sphere admits no flat metric, no matter how you deform it — and this is a theorem, not a failure of imagination.
This is the first meeting of a reading seminar on surface geometry, following O'Neill's Elementary Differential Geometry. Calculus III and linear algebra are the only prerequisites, and later talks will be given by participants. Everyone is welcome.

Ray Treinen will start a mini course on radial basis functions. We will have some theoretical results, but the primary goal of this mini course is to develop an understanding of how to use these functions in an interpolation scheme suitable for approximating solutions to partial differential equations.
