In this course we will study the continuous time nonlinear stochastic filtering problem and some of its applications to mathematical finance.
The program, time permitting, will be the following:
- Introduction of the problem
- The filtering problem as a measure valued random evolution.
- Review on stochastic processes and stochastic integration.
-The filtering equations: the Zakai and Kushner-Stratonovich equations.
- Properties of the solutions of the filtering equations.
- Finite dimensional filters: the Benes and Kalman-Bucy filter.
- Numerical methods: particle filters.
- Basics on discrete time stochastic filtering.
- Applications to mathematical finance.
