We study the motion of a Brownian particle in a bistable potential for intermediate and high-friction \(\gamma\). We perform a high-friction expansion of the distribution function P(v,x,t) in velocity and space. We show (for arbitrary potential) that the expansion coefficients obey simple recursion relations, which allow them to be calculated easily.
