Lawton, Wayne Global analysis of wavelet methods for Euler’s equation. (English) Zbl 1024.76007 Mat. Model. 14, No. 5, 75-88 (2002). Summary: Euler’s equation for the velocity \(u\) of an inviscid incompressible flow on Euclidean space admits the weak formulation \((\dot u,v)= ([u,v],u)\), for all divergence-free vector fields \(v\). Here \((\cdot, \cdot)\) denotes the scalar product that represents kinetic energy, and \([\cdot, \cdot]\) denotes the Poisson bracket. We employ global analysis methods based on this formulation to discuss Faedo-Galerkin approximation using divergence-free wavelets.
