Summary: This research investigates the characteristics of localized waves propagating from an electron-ion plasma to an electron-ion-dusty plasma region. The presence of dust particles is considered as a weak perturbation in the medium. The study shows that the ion-acoustic wave propagates with a higher velocity and energy when interacting with dust particles. Additionally, an oscillatory shock wave is created at the border of two different plasma environments, propagating in the opposite direction of the initial wave velocity. The time evolution of solitary waves and the characteristics of the generated shock profile are also studied.

Summary: In this paper, the behavior of dust acoustic waves in a nonconstant dust temperature plasma was investigated. The model considered negatively charged dust particles and thermal ions. The reductive perturbation technique was applied and the novelty of this study lies in the nonuniformity of plasma temperature. The nonconstancy of temperature was introduced as a first-order perturbation in the calculations, leading to the derivation of the modified Korteweg-de Vries (mKdV) equation. The solution of the modified KdV equation revealed the changes in soliton shape when the wave propagated in a perturbation plasma with varying temperature. Effects such as soliton deformation and amplitude reduction were observed when encountering regions with different temperatures. This research contributes to a better understanding of wave behavior in real plasmas with nonuniform temperature.

Summary: The influence of polarization force, trapped degenerate electrons, and nonthermal ions on the propagation characteristics of dust acoustic solitary waves (DASWs) in a magnetized dusty plasma is investigated. The reductive perturbation approach has been used to derive the extended Zakharov-Kuznetsov (eZK) equation and study the characteristics of DASWs. Pulse stability has also been analyzed, and the impact of different plasma parameters on the growth rate and instability criteria of DASWs has been studied. This investigation is important for explaining nonlinear structures in ultra-dense degenerate plasma media found in astrophysical compact objects and high-density plasma experiments.

Summary: This research uses the pseudopotential method to study the properties of dust-ion-acoustic (DIA) solitons in an unmagnetized dusty plasma. An important finding is that DIA solitons exist beyond certain critical values of the electron-to-ion density ratio and the superthermal parameter of electrons. The study results contribute to a better understanding of the behavior of dust-ion waves in various spaces.

Summary: A theoretical investigation was conducted to study the propagation of dust-acoustic solitary waves in a dusty plasma system. The study considered dynamic positively and negatively charged warm dust species, as well as nonthermally distributed ion and electron species.

Summary: This paper studies the propagation of envelope soliton through the nonlinear transverse dust grain displacement in dusty plasma crystals. By establishing the linear dispersion and the nonlinear Schrodinger equation, the study found an additional regime of the formation of dark soliton when choosing a gap frequency value close to the experimental value. The prediction of group velocity was confirmed through numerical and experimental studies. This work makes a significant contribution to the field of dusty plasma crystals.

Summary: Different nonlinear dynamical behaviors of dust-acoustic modes in a homogeneous plasma were examined using a 3D-NLS equation. Various methods, including bifurcation analysis and factorization method, were employed to explore the solutions of the equation, including periodic, shocklike, and explosive waves. Additionally, the study also investigated the rogue wave solution and its dependence on nonextensivity parameters, which can have implications for electrostatic structures in dusty plasmas like Saturn's E-ring.

Summary: The study focuses on the properties of the dust-acoustic solitary waves in a complex magnetoplasma consisting of negatively charged moving dust grains, inertialess electrons, and ions obeying Maxwell and kappa distributions in the lower ionospheric region. The reductive perturbation technique is used to obtain the Zakharov-Kuznetsov (ZK) equation within the given framework. The obtained ZK equation is transformed into a planar dynamical system to study the qualitative behavior of the solitary waves. Numerical investigations are conducted to examine the influence of important physical parameters on the profile of the nonlinear structures. The findings contribute to the understanding of low-frequency irregularities in the lower ionosphere.

Summary: The existence and propagation of dust acoustic waves in quantum four-component plasma were investigated using the Sagdeev pseudo-potential. It was found that the equation is difficult to integrate due to the complexity of the Sagdeev potential.

Summary: This study investigates the modulational instability of finite amplitude dust-ion acoustic nonlinear waves in a six-component cometary dusty plasma using a nonlinear Schrodinger-type equation. The results reveal two parametric domains where the dust-ion acoustic waves are modulationally stable or unstable depending on the plasma configurational parameters. Rogue waves could be generated within the unstable domain, and the effects of pertinent plasma parameters on the profile of rogue waves are studied.
