An equation of the form

that is, a condition imposed on the transition function (, , , being a measurable space), enabling one (under certain conditions on ) to construct a Markov process for which the conditional probability is the same as . Conversely, for a Markov process its transition function , which by definition is equal to , satisfies the Kolmogorov–Chapman equation, as follows immediately from general properties of conditional probabilities. This was pointed out by S. Chapman [1] and investigated by A.N. Kolmogorov in 1931 (see [2]).

Comments

In Western literature this equation is usually referred to as the Chapman–Kolmogorov equation.
