Nonplanar positron-acoustic Gardner solitary waves in electron-positron-ion plasmas with superthermal electrons and positrons (original) (raw)

This paper investigates the existence and properties of nonplanar positron-acoustic Gardner solitary waves in electron-positron-ion plasmas that include superthermal electrons and positrons. The study highlights significant differences in the behavior of positron-acoustic waves in comparison to traditional electron-ion plasmas, particularly in different geometric configurations (planar, cylindrical, and spherical). Through analysis and figures, the paper presents the influence of parameters on the formation and stability of these solitary waves in various plasma conditions.
