New application of Adomian decomposition method on Fokker–Planck equation

Adomian decomposition method has been used for finding the explicit and numerical solutions of the reduced Fokker Planck equation in a force field. The obtained results are compared with those found by other theories such as Lie group theory. The behaviour of the approximate distribution functions are shown graphically. The results of Lie group method confirm the correctness of those obtained by Adomian decomposition method.
