Introduction to topological data analysis In this talk I'll give a tour of how ideas and tools from topology are helping to provide important new methods of visualising, analysing, and exploring complex and high dimensional data sets. I'll describe the Mapper algorithm of Ayasdi and some of its applications, and then introduce persistent homology and

Title: Cones and symmetries of projective varieties Abstract: A smooth projective variety can be viewed as a compact manifold, but its cohomology groups have extra structure: the classes of subvarieties of a given dimension span a convex cone in the relevant (real) cohomology group. For some classes of varieties these cones are easy to compute,
