Comment on "Head-on collision of electron acoustic solitary waves in a plasma with nonextensive hot electrons"

TL;DR

This paper critiques a previous study on electron acoustic solitary wave collisions, highlighting deficiencies in their analysis that led to incorrect conclusions about the behavior of these waves in plasma with nonextensive hot electrons.

Contribution

It provides a critical analysis of prior work, correcting methodological errors and clarifying the true nature of wave collisions in nonextensive plasma environments.

Findings

Previous conclusions were erroneous due to methodological flaws.

Corrected analysis clarifies wave collision dynamics.

Highlights importance of proper treatment in nonlinear plasma studies.

Abstract

In a recent paper "Head-on collision of electron acoustic solitary waves in a plasma with nonextensive hot electrons" [Astrophys. Space Sci. 338, 271-278 (2012)] Eslami, Mottaghizadeh and Pakzad deal with the problem of the head-on collisions between two weakly nonlinear electron-acoustic solitary waves. Unfortunately, their treatment is deficient and leads to erroneous conclusions.
