Transition probability.

Each transition adds some Gaussian noise to the previous one; it makes sense for the limiting distribution (if there is one) to be completely Gaussian. ... Can we use some "contraction" property of the transition probability to show it's getting closer and closer to Gaussian ? $\endgroup$
