Information and Entropy
Section 14.1 presents the definitions and key properties of information and entropy. Section 14.2 discusses the entropy of a (stationary) finite Markov chain. The Law of Large Numbers is proved for the amount of information contained in a message that is a long sequence of successive states of a Markov chain, and the asymptotic behaviour of the number of the most common states in a sequence of successive values of the chain is established. Applications of this result to coding are discussed.
