Learning outcomes

After successful completion of the course, students are able to ...

  • explain and apply the chain rule, integration by parts, and convergence theorems for stochastic integrals (w.r.t. continuous semimartingales),
  • formulate and use Ito's multidimensional formula, Tanaka's formula, lto's local formula and Ito's formula for holomophic functions, present selected applications,
  • introduce the stochastic exponential and the stochastic logarithm, explain basic properties and characterisations, 
  • use Lévy's characterization of Brownian motion, 
  • formulate Girsanov's theorem and apply it to adjust the drift of Brownian motion by a measure change, 
  • explain Doob's upcrossing inequality and derive Doob's convergence theorems for submartingales,
  • explain and apply the predictable integral representation theorem for Brownian local martingales, 
  • check and derive conclusions from Kazamaki's and Novikov's criterion,
  • describe and apply the ideas and methods used to prove tha main theorems of the course.
