“…It was discovered that the shock wave shapes are considerably altered by the presence of positrons in plasma. Various models are used to explore the motion of electrostatic solitary waves in e-p-i plasma in multiple studies [8][9][10][11][12][13]. Many studies of ion acoustic solitons (IASs) in electron-positron-ion (e-p-i) plasmas have been described in recent years [14][15][16][17][18][19][20][21][22].…”

The process of propagation of cylindrical and spherical ion acoustic solitary waves in an electron, positron, and ion plasma system is studied. The electrons are considered to have the generalized (r; q) distribution, while the positrons are supposed to have the kappa distribution, also known as the Lorentzian distribution. The classic nonlinear equation, Korteweg de-Vries (KdV), has been numerically solved by employing appropriate mathematical transformations. The role of various plasma parameters and nonplanar geometry on the widths and amplitudes of nonlinear ion acoustic structures has been numerically investigated. The current study could be helpful to understand the significance of cylindrical and spherical solitary waves in astrophysical as well as in space plasmas.

“…[46,47] KP equation is such an integrable equation and hence Ma et al [48] has obtained a class of lump solutions to the (2 + 1)-dimensional Kadomtsev-Petviashvili (KP) equation by using Hirota bilinear form. The wide prevalence of lump soliton solutions to nonlinear evolution equations, specifically to KP equation, attracts many researchers [49][50][51][52] to reveal its impressive nonlinear significance.…”

Soliton theory is a very efficient and competent way to describe nonlinear features. Using Hirota bilinear method, we have obtained a lump soliton solution of the Kadomstev-Petviashvili equation which is the reduced canonical form of the collisionless quantum electron-positron-ion magnetoplasma system. Due to its wide range of applications, the study of lump soliton structures is very much attractive and important. The amplitude of lump solitons is varied for different system parameters. During the analysis of the features of the lump solitons, it is found that the quantum diffraction parameter (H e ), statistical temperature ratio (𝜎), positrons number density (𝜇 p ), magnetic intensity parameter (Ω) have a considerable impact on the lump solitons structures. Compressive as well as rarefactive lump soliton has been found during the investigation.

The propagation properties of planar and non‐planar electron acoustic shock waves composed of stationary ions, cold electrons, and q‐non‐extensive hot electrons and positrons are studied in unmagnetized electron‐positron‐ion plasma. In this model, the Korteweg‐de Vries Burgers equation is obtained in the planar and non‐planar coordinates. We have investigated the combined action of the dissipation, non‐extensivity, density ratio of hot to cold electrons, concentration of positrons, and temperature difference of cold electrons, hot electrons, and positrons. It was found that the amplitude of shock wave in e‐p‐i plasma increases when the positron concentration and temperature increase. The same effect is observed in the case of kinematic viscosity η. Furthermore, it is noticed that spherical wave moves faster in comparison to the shock waves in cylindrical geometry. This difference arises due to the presence of the geometry term m/2τ. It should be noted that the contribution of the geometry factor comes through the continuity equation. Results of our work may be helpful to illustrate the different properties of shock wave features in different astrophysical and space environments like supernova, polar regions, and in the vicinity of black holes.
