Below is an illustration of a Markov Chain were each node represents a state with a probability of transitioning from one state to the next, where Stop represents a terminal state. The random telegraph process is defined as a Markov process that takes on only two values: 1 and -1, which it switches between with the rate γ.

A stochastic process is a sequence of events in which the outcome at any stage depends on some probability. Definition 2. A Markov process is a stochastic process with the following properties: (a.) The number of possible outcomes or states Discrete Markov chains: definition, transition probabilities (Ch 1, 2.1-2.2). Discrete Markov processes: definition, transition intensities, waiting times, embedded Markov chain (Ch 4.1, parts of 4.2).

A Markov process is a random process in which the future is independent of the past, given the present. Thus, Markov processes are the natural stochastic analogs of the deterministic processes described by differential and difference equations. They form one of the most important classes of random processes process (given by the Q-matrix) uniquely determines the process via Kol-mogorov’s backward equations.
Content. The Markov property. Chapman-Kolmogorov's relation, classification of Markov processes, transition probability. Transition intensity, forward and backward equations.
