MATH40480 Stochastic Analysis

Academic Year 2020/2021

Probability theory has its roots in games of chance, such as coin tosses or throwing dice. By playing these games, one develops some probabilistic intuition. Such intuition guided the early development of probability theory and allowed for rigorous statements to be made concerning such games as well as more complex situations such as the evolution of stock prices.

In this course, we will develop the mathematical tools required to study sequences of real-valued random variables. We will use these tools to study some of the most central objects in probability: the laws of large numbers, the central limit theorem and the martingale. We will then see how these can be used to model real-world applications such as betting strategies.

Learning Outcomes:

On the completion of this module the student should be familiar with the fundamental concepts of Probability Theory which lead towards the deep mathematical theory of Stochastic Analysis. This includes independence, expectation, conditional expectation, stochastic processes, filtrations, martingales.
The student will develop his or her ability to deal with abstract concepts and to relate them to real world examples. The student's ability to realise and critique proofs and arguments will be enhanced.

Indicative Module Content:

Measure theoretic approach to probability theory; types of convergence for random sequences; independence of sigma algebras; Borel-Cantelli lemmas; laws of large numbers; central limit theorems; conditional probability and expectation; martingale convergence theorems; optional stopping theorems for martingales.
