On the Equation of Diffusion [PDF]
Proceedings of the National Academy of Sciences, 1937 Under the title "The Analytical Theory of Probability," A. Kolmogoroff [1] published a few years ago a mathematically elegant account of what might be called the general theory of diffusion. As the main result of his analysis, he sets up two differential equations for transition probabilities (see below).
