Course content

This course will be split into two parts. Firstly we shall consider the path structure of a general Lévy process, in particular we shall look at the classical Lévy-Ito decomposition. From this we shall consider the special cases of subordinators and spectrally one-sided Lévy processes. We will discuss some additional properties of these processes in particular the latter. In the second part of the course we will look at a particular application of spectrally one-sided Lévy processes to the theory of continuous state branching processes. In particular we shall see how certain path properties of spectrally negative processes allow us to understand the behaviour of continuous state branching processes. Some key topics are given below.

Assessment will be on the basis of a take-home exam at the end.

The course is based on the following graduate text book below.
