Ehrenfest chain. Consider the Ehrenfest chain, Example 1.2, with transition
From this we see that the mean n converges exponentially rapidly to the equilibrium value of N/2 with the error at time n being (1 – 2/N)n(x – N/2).
(Ehrenfest Chain). This chain originated in physics as a model for two cubical volumes of air connected by a small hole. In the mathematical version, we have two “urns,” i.e., two of the exalted trash cans of probability theory, in which there are a total of N balls. We pick one of the N balls at random and move it to the other urn.
