5.00 credits
30.0 h
The courses MAT1322 Measurement Theory and MAT1371 Probability are an absolute prerequisite

Learning outcomes

At the end of this learning unit, the student is able to :

  • To choice the most adapted process for modeling a random phenomenon.
  • To analyze the properties of discrete and continuous processes.
  • To construct martingale processes.
  • To analyze the stability of a Markov chain.
  • To use Poisson counting processes, homogenous and non-homegenous
  • To infer the infinitesimal dynamics of a function driven by a Brownian motion, with the help of stochastic calculus.
This course is a detailled introduction to stochastic processes in discrete and continuous time:
Part I:
  1. Revision of probability theory
  2. Martingales in discrete time
  3. Markov Chaine in discrete time and with a finite number of states
Part II:
  1. Poisson processes and Poisson measures
  2. Continuous Markov process with a finite number of states
  3. Brownian motien & Itô's calculus
  4. Continuous time martingales
  5. Continuous Markov processes with infinite number of state
