W, F 1-1.50 p.m. and by appointment.

Stochastic differential equations arise in modelling a variety of
random dynamic phenomena in the physical, biological,
engineering and social sciences. Solutions of these
equations are often diffusion processes and hence are connected to the
subject of partial differential equations.
This course will present the basic theory of stochastic differential equations
and provide examples of its application.
1. A review of the relevant stochastic process and martingale theory.
2. Stochastic calculus including Ito's formula.
3. Existence and uniqueness for stochastic differential equations, strong
Computer modules for
performing symbolic manipulations in stochastic calculus and for
numerically approximating the solutions of stochastic differential equations
will be made available to complement the theoretical material
presented in the course. These modules make use of
