On Perturbation theory for the Fokker--Planck equation

TL;DR

This paper examines the application of the Modified Homotopy Perturbation Method to the Fokker-Planck equation, highlighting that the examples used are not physically relevant.

Contribution

It critically analyzes the use of a perturbation method on the Fokker-Planck equation and questions the physical applicability of previous examples.

Findings

Examples lack physical relevance

Method's applicability is limited to non-physical cases

Highlights need for physically meaningful problem selection

Abstract

We discuss a recent application of the Modified Homotopy Perturbation Method to the Fokker--Planck equation and show that the selected examples do not have any connection with actual physical problems.
