Wavelet representation of light-front quantum field theory

Understand

A formally exact discrete multi-resolution representation of quantum field theory on a light front is presented.

• The formulation uses an orthonormal basis of compactly supported wavelets to expand the fields restricted to a light front.
• The representation has a number of useful properties.
• First, light front preserving Poincar\'e transformations can be computed by transforming the arguments of the basis functions.
