# SM4202 Random Processes

I will be teaching SM4202 for the first half of the semester (roughly 7 weeks) for the August 2020 semester.

### Syllabus

Here are the topics I intend to cover for this course. This may change depending on how we get on with the course.

Chapter 1: Probability recap

- Recall fundamental concepts in mathematical probability
- Recap of discrete and continuous distributions
- Properties of means and variances
- Generating functions

Chapter 2: Discrete time stochastic processes

- Definitions and examples
- Discrete Markov chains
- Transition probabilities, stationary transition probabilities, $n$-step transition matrices
- Chapman-Kolmogorov equations
- State diagrams and classification of states
- Periodicity, recurrence and transience

Chapter 3: Continuous time stochastic processes

- Basic concepts and definitions
- Instantaneous transition rates
- $Q$ matrices (generator matrices)
- Kolmogorov equations
- Invariant measures for irreducible, continuous Markov processes
