Within the course we present an introduction to the theory of Lévy processes, we learn about the probabilistic approach to the potential theory and partial differential equations, and finally we meet the basics of stochastic differential equations.

Knowledge and understanding:

Deepening of study and rigorous treatment of certain particular features of stochastic processes, probabilistic approach to problems from PDE.

Application:

Basic tools for modelling in many branches of

mathematics and its applications.

Reflection:

Learning about deeper connections between various areas of mathematics, meticulous treatment of jumps.

Transferable skills:

The skills acquired are transferable to other areas of mathematical modelling, among the rest to financial models.

Lectures, exercises, homeworks, seminars

Homework and seminar assignments

Oral exam

grading: 5 (fail), 6-10 (pass) (according to the Statute of UL)
