| contents | Perturbing the arrangements of pegs on a static Galton board can result in non-trivial stationary distributions, which in the continuum limit correspond to departure from regular gaussian behavior. Two such distributions are obtained. Further, the distributions generated for a dynamic galton board under external forcing in a general direction are obtained by solution of the corresponding stochastic differential equations. Exact cumulant generating functions for the distribution are presented for forcing in one dimension. An approximate expression, correct to first order in the forcing amplitude, is presented for the case of two dimensions. Both cases show nontrivial departures from the static gaussian solution. |
