Terry Lyons, Oxford: "Rough paths"

Abstract:

There will be three lectures, the first will consider the signature of a path; the second will look at the general theory of rough paths, explaining the most basic theorems; the third will look at how the signature of a path, together with a re-combination technique, can be used to produce high order substitute methods for Monte Carlo. Putting these ideas together one is able to create a family of novel and very accurate numerical methods.
