Research
The research of our group focuses on the theoretical and statistical questions for stochastic processes, such as
- stochastic differential equations (with jumps)
- Lévy processes
- branching processes
- self-similar Markov processes
These processes are central in the growth of probability theory during the past decades and have various applications in industry for instance in insurance and banking.
