Kolmogorov Equations
As usual let us again consider as the Markov process in continuous time and continuous state set up such that the following assumptions are considered to be true:
,
, where is the drift coefficient.
, where is the diffusion coefficient.
Then the corresponding forward Kolmorogov equation and backward Kolmorogov equation are given by:
Note
- In case
then the Markov process is homogeneous and we have and , i.e., both are independent of time .
- If the Markov process is additive, then
depends only on and and not on , hence and we have and , i.e., both are independent of time .
