Stochastic processes form a basis for numerous models in finance and insurance. The course links theoretical parts learned in other courses on stochastic processes by showing their applications on one side and elucidates
the theoretical background on the other.
Since the content is of great practical importance we expect that also specialists from financial practice will present their work experience during the course.
Knowledge and understanding: Understanding of stochastic modelling in finance and insurance and understanding of mathematical framework.
Application: Application is immediate as the models under consideration form a basis for
Pricing many financial and insurance products.
Reflection: The application of stochastic processes deepens the knowledge of probability calculus and stochastic processes and paves the way for their application.
Transferable skills: The skills obtained are transferable to other areas of mathematical modelling, but the gist of the course is its immediate applicability.
