Short course on theory of rough paths by Dr. Christian Bayer (Weierstrass Institute)

Rough paths and rough partial differential equations

Terry Lyons' theory of rough paths provides a framework for a
deterministic solution theory for rough differential equations,
i.e., differential equations driven by a signal which is rougher
than 1/2-Hölder. This includes stochastic differential equations
of Ito or Stratonovich type. The theory is not restricted to
finite dimensional differential equations, but can also be
applied to partial differential equations driven by finite or
infinite dimensional signals. Moreover, the solution is generally
a continuous function of the input (rough) signal in rough path
topology.

In this mini-course we provide a short, condensed development of
the theory of rough paths. We consider the following topics:

1) Motivation and introduction
2) Rough path spaces
3) Integration against rough paths
4) Rough differential equations
5) Rough partial differential equations
