Wiener-Hopf technique

The Wiener-Hopf technique is a mathematical method used to solve certain types of problems involving equations that split into parts, often found in fields like engineering and physics. It works by transforming a complex problem into simpler pieces, solving each piece individually in a way that makes the overall problem manageable. This approach often involves breaking down functions into parts that are easier to analyze—those that behave well in different regions of the complex plane—and then recombining them to find a solution. It's a powerful tool for tackling boundary value problems and integral equations in a systematic way.
