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.
See also (the editorial comments to) Einstein–Smoluchowski equation.
