Summary: In this study, we investigate the x-nonlocal Davey-Stewartson II equation using the Kadomtsev-Petviashvili hierarchy reduction method. We report the discovery of dark solitons and (semi-) rational solutions expressed in the Gram-type determinant. These analytical solutions are then used to study the evolution scenarios of dark/anti-dark solitons on nonzero backgrounds. Additionally, we analyze the elastic interactions between different types of solitons through asymptotic analysis.

Summary: The anomalous scattering phenomena of lump waves within the Mel'nikov equation framework are investigated using Hirota's bilinear method and further constraints. The study examines the detailed behavior of anomalous scattering of two lumps and discusses the asymptotic behavior of anomalous scattering lumps. Additionally, the study observes several intriguing structures of high-order degenerate lumps, including triangular and quadrangular peak locations. These findings enhance our understanding of the nature of lump waves.

Summary: Based on the KP-hierarchy reduction method, we constructed a novel bright-dark mixed N-soliton for the (3 + 1)-component Mel'nikov system and discussed two types of solitons based on different combinations. Finally, we extended the model to a multi-component case and provided the generalized form of the bright-dark mixed N-soliton in Gram determinant form.

Summary: In this study, general soliton and (semi-)rational solutions to the y-non-local Mel'nikov equation with non-zero boundary conditions are obtained using the Kadomtsev-Petviashvili (KP) hierarchy reduction method. The solutions are expressed in N x N Gram-type determinants with an arbitrary positive integer N. It is found that there are two families of constraints among the parameters appearing in the solutions, leading to different behaviors in generating solitons and lumps.

Summary: In this paper, we investigate rational and semi-rational solutions to the third-type Davey-Stewartson (DS III) equation and its nonlocal version using Hirota's bilinear method and long wave limit technique. Rational solutions to the DS III equation include kinks, lumps, and line rogue waves, while semi-rational solutions exhibit hybrids of solitons, lumps, and line rogue waves. For the nonlocal DS III equation, we obtain (semi-)rational solutions and breather solutions, which show lumps on periodic line backgrounds, hybrids of breathers and lumps, line rogue waves, and line breathers on periodic line backgrounds.

Summary: In this paper, the KP hierarchy reduction method is applied to investigate the rational and semi-rational solutions of the (2 + 1)-dimensional Maccari system. The study shows that two types of breathers can be derived, and these solutions can be reduced to well-known solutions under certain parameter constraints. The interactions between the solutions are further discussed, and a new three-state interaction is provided.

Summary: This paper investigates the coherent structures of two-dimensional lump-solitons for the Mel'nikov equation, utilizing the Hirota bilinear method and Kadomtsev-Petviashvili hierarchy reduction method to construct specific solutions displaying various coherent waves. In contrast to traditional lumps, the lumps within the coherent structures of lump-solitons are localized not only in two-dimensional space but also in time.

Summary: Multiple dark and antidark soliton solutions for a space shifted PT symmetric nonlocal nonlinear Schrodinger equation are constructed and classified using the Kadomtsev-Petviashvili hierarchy reduction method and Hirota's bilinear technique. The amplitude values and collision coordinates of two-soliton solutions are discussed theoretically and numerically, and the parameter conditions of these solutions are given. Furthermore, the four-soliton solutions show a superposition of two two-soliton solutions, indicating that higher-order soliton solutions should have similar properties.

Summary: In this work, the higher-order breather, periodic-wave, lump, rational soliton solutions, and mixed solutions of the Hirota-Maccari (HM) system are investigated. The Kadomtsev-Petviashvili (KP) hierarchy reduction method is employed to analyze the structural characteristics of these solutions. The study reveals the quasi-periodic W(M)-shaped waves and two types of breathers in the periodic-wave solutions. Mixed solutions, consisting of the quasi-periodic W(M)-shaped waves and breathers, are constructed. The characteristics and generating conditions of these mixed solutions are discussed, and a new bound-state interaction composed of a lump and a breather is discovered.

Summary: We constructed resonant lump chain solutions to the Mel'nikov equation using the Hirota bilinear approach, which involve resonance between lump chains and resonance between lump and lump chains. Our study shows that the resonant interaction of these chains leads to infinite phase shifts, similar to line soliton interactions in the Kadomtsev-Petviashvili-II equation. The interactions are classified into oblique and parallel cases depending on the velocities of the individual lump chains. We also observed obliquely collided lump chains with a Y-shaped structure and identified parallel resonance of lump chains leading to transmission, splitting, or absorption of another lump chain. Additionally, the interactions between lump and lump chains can be semi-localized or completely localized in time.
