ST435 Half Unit
Advanced Probability Theory
This information is for the 2012/13 session.
Dr. Erik Baurdoux COL 6.04
This course is an option on MSc Risk and Stochastics, MSc Statistics (Financial Statistics) and MSc Statistics (Financial Statistics) (Research). It is available for Postgraduate taught and Research students across the School, timetabling permitting. The course is offered as a regular examinable half-unit as well as a service to students and academic staff.
Analysis and algebra at the level of a BSc in pure or applied mathematics and basic statistics and probability theory with stochastic processes. Knowledge of measure theory is not required as the course gives a self-contained introduction to this branch of analysis.
The course covers core topics in measure theoretic probability and modern stochastic calculus, thus laying a rigorous foundation for studies in statistics, actuarial science, financial mathematics, economics, and other areas where uncertainty is essential and needs to be described with advanced probability models. Emphasis is on probability theory as such rather than on special models occurring in its applications.
Brief revision of mathematical tools: set theory, logics, techniques of proof, real and complex numbers, sequences, functions, metric spaces, notions of limits and convergence, continuity, differentiation and integration. Brief review of basic probability concepts in a measure theoretic setting: probability spaces, random variables, expected value, conditional probability and expectation, independence, Borel-Cantelli lemmas Construction of probability spaces with emphasis on stochastic processes. Operator methods in probability: generating functions, moment generating functions, Laplace transforms, and characteristic functions. Notions of convergence: convergence in probability and weak laws of large numbers, convergence almost surely and strong laws of large numbers, convergence of probability measures and central limit theorems. If time permits and depending on the interest of the students topics from stochastic calculus might be covered as well.
Thirty hours of lectures in the MT.
Exercises are set weekly and solutions are discussed in the lectures. There will be two rounds of compulsory written coursework which will be marked, one in the MT and one in the LT.
