Learning and Teaching Methods
lecture, exercise module
The module is offered as lectures with accompanying practice sessions. In the lectures, the contents will be presented in a talk with demonstrative examples, as well as through discussion with the students. The lectures should motivate the students to carry out their own analysis of the themes presented and to independently study the relevant literature. Corresponding to each lecture, practice sessions will be offered, in which exercise sheets will be available.
In this way, students can deepen their understanding of the methods and concepts taught in the lectures and independently check their progress.

Module Exam
Description of exams and course work
The module examination is based on a written exam (60-90 minutes).
Students have to know and understand the theoretical foundations of Brownian motion, the theory of continuous martingales and Lévy's representation and characterisation Theorems. They also need to be able to understand the basics of stochastic integration and stochastic differential equations and to apply Itô's formula and change-of-measure techniques.
