  🌊 Linear Superposition Solutions of the Generalized (2+1)-Dimensional KdV Equation ✨ Introduction Nonlinear evolution equations play a crucial role in understanding wave propagation in physics, engineering, and applied mathematics. Among them, the  generalized (2+1)-dimensional Korteweg–de Vries (KdV) equation  is especially important for modeling wave motion in fluids, plasmas, and other nonlinear media. This equation extends the classical KdV equation into higher dimensions, allowing researchers to study more realistic and complex wave behaviors. 🔬 What is Linear Superposition? In linear systems,  superposition  means multiple waves can combine, and the total solution is simply their sum. However, nonlinear systems typically do not follow this rule. Interestingly, this research demonstrates  exact linear superposition solutions even within a nonlinear framework , revealing special conditions where: Multiple waves coexist 🤝 Each wave maintains its ide...

Introduction High-temperature superconducting (HTS) technologies are increasingly recognized as key enablers for next-generation large-capacity rotating electrical machinery due to their superior current density, reduced losses, and compact design potential. A critical challenge in realizing practical HTS-based systems lies in the cryogenic infrastructure required to maintain superconductivity under operational conditions.
