### Course Objectives

Students shuould acquire a good knowledge of advanced probabilistic tools employed in the modeling of
financial markets.
In particular they should become able to
- learn and understand the first mathematical models involving stochastic calculus techniques;
- solve derivatives evaluation problems of medium difficulty;
- extend the studied notions to more complex models;
- read an advanced text in financial modeling;
- implement computations for the studied models.

### Course Content
