Query: Invariant closure for the Fokker-Planck equation   We develop the principle of dynamic invariance to obtain closed moment
equations from the Fokker-Planck kinetic equation. The analysis is carried out
to explicit formulae for computation of the lowest eigenvalue and of the
corresponding eigenfunction for arbitrary potentials.
