# Introduction to Stochastic Analysis

## Unit aims

The unit aims to give a rigorous yet non-technical introduction to Brownian motion, with an emphasis on concrete calculations and examples.

## Unit description

The course is intended for Master's students with a sufficiently strong background in analysis. Construction and analytic properties of Brownian motion, stochastic integration, stochastic differential equations and their strong and weak solutions, various approaches to diffusion processes will be covered. These are all topics of central importance in the general advanced mathematical culture. Special emphasis will be put on various applications of the theory.

## Relation to other units

This is a new unit for 2018/19.

## Learning objectives

• To gain a good understanding of the basic notions and techniques of the theory of:
• Brownian motion;
• Stochastic differential equations and their strong and weak solutions;
• Diffusion processes;
• Applications of these concepts.
• To prepare students for independent research in mathematics.
