DOI: 10.1002/andp.202200635
Abstract: Non‐linear electrodynamics (NLED) is a generalization of Maxwell's electrodynamics for strong fields. It has significant implications for the study of black holes and cosmology and has been extensively studied in the literature, extending from quantum… read more here.

DOI: 10.1002/ctpp.201900072
Abstract: In order to investigate the propagation characteristics of linear and non‐linear ion acoustic waves (IAWs) in electron–positron–ion quantum plasma in the presence of external weak magnetic field, we have used a quantum hydrodynamic model, and… read more here.

DOI: 10.1002/ctpp.202000225
Abstract: We used a new distribution of electrons in a two‐component magnetized plasma to study the non‐linear ion‐acoustic solitary structures. The distribution called “Cairns–Gurevich distribution” describes simultaneously the evolution of the energetic electrons and those trapped… read more here.

DOI: 10.1002/esp.4096
Abstract: Geomorphic effectiveness has been an influential concept in geomorphology since its introduction by Reds Wolman and John Miller in 1960. It provided a much needed framework to assess the significance of an event by comparing… read more here.

DOI: 10.1002/mma.5829
Abstract: In this paper, a novel approach, namely, the linearization‐based approach of homotopy analysis method, to analytically treat non‐linear time‐fractional PDEs is proposed. The presented approach suggests a new optimized structure of the homotopy series solution… read more here.
