Spectral decomposition of 3D Fokker - Planck differential operator
Abstract
Description
We construct spectral decomposition of 3D Fokker - Planck differential operator in this paper. We use the decomposition to obtain solution of Cauchy problem - and especially the fundamental solution. Then we use the decomposition to calculate macroscopic parameters of Fokker - Planck flow.
We correct expressions (48-54), (57-58), (71-73) - we replace $n sub j$ with $p sub j$ and ${omega sub j} over {a sub j}$ with $omega sub j$. Removed $a sub 1, a sub 2, a sub 3$ multiplier in (48-54) and (A4). We add APPENDIX with formulae for the case of unbounded space. Added reference to P. Resibois and M. De Leener work
