Abstract :
We generate conservation laws for the one dimensional nonconservative Fokker Planck
(FP) equation, also known as the Kolmogorov forward equation, which describes the time
evolution of the probability density function of position and velocity of a particle, and
associate these, where possible, with Lie symmetry group generators. We determine the
conserved vectors by a composite variational principle and then check if the condition for
which symmetries associate with the conservation law is satisfied. As the Fokker Planck
equation is evolution type, no recourse to a Lagrangian formulation is made. Moreover, we
obtain invariant solutions for the FP equation via potential symmetries.
