Content and learning outcomes
Course contents
Discrete and Continuous-time martingales, Wiener process, Stochastic integrals, Itô's lemma, Stochastic differential equations, exponential martingales, Girsanov transformation and its applications, Random time changes.
Intended learning outcomes
To pass the course, the student should be able to do the following:
- Be able to define and account for conditional expectation, filtrations and the martingale property in discrete and continuous time.
- Account for the properties of the Brownian motion (Wiener process), with applications.
- Define and account for Itô's stochastic integrals, the Itô lemma, Girsanov transform, the Martingale Representation Theorem and random time-change of Itô integrals in concrete situations.
- Account for and determine strong and weak solutions of stochastic differential equations of Itô type (diffusion processes).
- Account for and determine stochastic representations of solutions of parabolic partial differential equations (Kolmogorov's forward and backward equations, the Feynman-Kac and Dynkin's formulas).
To receive the highest grade, the student should in addition be able to do the following:
- Combine all the concepts and methods mentioned above in order to solve more complex problems.

Ethical approach
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
