Department: Mathematical Sciences

MATH3251: STOCHASTIC PROCESSES III

Type Level Credits Availability Module Cap Open 3 20 Available in 2021/22 Durham

Prerequisites

• Analysis in Many Variables II (MATH2031) AND Probability II (MATH2647)

• None.

Excluded Combination of Modules

• Stochastic Processes IV (MATH4091).

Aims

• This module continues on from the treatment of probability in Probability II (MATH2647).
• It is designed to introduce mathematics students to the wide variety of models of systems in which sequences of events are governed by probabilistic laws.
• Students completing this course should be equipped to read for themselves much of the vast literature on applications to problems in physics, engineering, chemistry, biology, medicine, psychology and many other fields.

Content

• Probability revision.
• Branching processes.
• Coupling.
• Martingales and applications.
• Poisson processes.
• Continuous-time Markov chains.
• Brownian motion.
• Additional topics in stochastic processes.

Learning Outcomes

Subject-specific Knowledge:
• By the end of the module students will: be able to solve novel and/or complex problems in Stochastic Processes.
• have a systematic and coherent understanding of theoretical mathematics in the field of Stochastic Processes.
• have acquired coherent body of knowledge of these subjects demonstrated through one or more of the following topic areas:
• Probability.
• Discrete Parameter Martingales.
• Brownian motion.
• Poisson processes.
• Continuous-time Markov processes.
• Coupling.
Subject-specific Skills:
• In addition students will have specialised mathematical skills in the following areas which can be used with minimal guidance: Modelling, Computation.
Key Skills:

Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

• Lectures demonstrate what is required to be learned and the application of the theory to practical examples.
• Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
• Formatively assessed assignments provide practice in the application of logic and high level of rigour as well as feedback for the students and the lecturer on students' progress.
• The end-of-year examination assesses the knowledge acquired and the ability to solve predictable and unpredictable problems.
