The Landau-Lifshitz series

The Landau-Lifshitz series is a mathematical approach used in physics to approximate the behavior of a particle or system when it is influenced by multiple factors, such as forces or fields, especially when some effects are small but complex to calculate exactly. It breaks down these influences into a series of increasingly refined corrections, helping scientists predict how systems evolve over time with better accuracy. Essentially, it’s a method to iteratively improve our understanding of a system’s motion by considering small effects step-by-step.
