Abstract
Nonlinearly interacting waves are often described by asymptotic equations. The derivation typically involves an ansatz for an approximate solution where higher order terms – the precise meaning of higher order term depends on the context and the relevant scales – are neglected. Often a Taylor expansion of a Fourier multiplier is part of that process.
