Access Index ### Course description and aims

In this lecture, the theory of Ito integral (stochastic integral) is introduced. We start from the definition of the Ito integral and the Ito formula is introduced. Then we develop some important aspects of stochastic differential equations. As an application of Girsanov's theory and martingale representation, the Black-Scholes formula is derived.

### Student learning outcomes

Students are expected that they understand the notion of stochastic integral, are able to use the Ito formula properly, and understand the relations between the basic notion of the theory of mathmatical finance and stochastic integrals.
