Description To give a comprehensive introduction to Markov chains, Markov jump processes and their application to actuarial science.  
Learning Outcomes 1. Construct Markov chain models for actuarial and financial processes. 2. Analyse any given chain in a systematic way, including determining its asymptotic behaviour. 3. Prove the main theorems governing Markov chains in discrete and continuous time. 4. State the definitions of the main concepts underlying the theory of Markov chains and demonstrate an understanding of these through examples and counterexamples.
