This course is concerned with a rigorous introduction to the area of stochastic analysis with emphasis on Itô calculus. The course begins necessary preliminaries, followed by a construction of the standard Brownian motion and a study of its properties. Subsequently, Lévy’s characterisation of Brownian motion, martingale representation theorems and Girsanov’s theorem are established. The course then expands on a study of stochastic differential equations.

20 hours of lectures and 10 hours of seminars in the LT.
