Stochastic differential equations are increasingly important in many cutting-edge models in physics, biochemistry and finance. The aim of the course is to give the postgraduate student a fundamental knowledge and understanding of stochastic differential equations, emphasizing the computational techniques necessary for stochastic simulation in modern applications.

The course is divided into two parts, with the first dealing with classical theory for deterministic ordinary differential equations (ODEs) and the second with theory for stochastic differential equations (SDEs). The deterministic part reviews necessary background, in particular Runge-Kutta and Rosenbrock methods. The second part gives an introduction to SDEs, and presents basic ideas and techniques used in statistical simulation, such as root mean square stability; consistency notions; and weak and strong convergence. A few applications will be studied in more detail, including pertinent problems to be solved using a computer.

have a good understanding of the difference between stochastic and deterministic equations, and of Monte Carlo methods for stochastic simulation.

have a good understanding of weak and strong convergence, and of stability theory for stochastic differential equations.
be able to interpret stochastic differential equations and to give examples of models that include them.

be able to independently implement discretization schemes for stochastic differential equations and critically evaluate the results.
