Abstract
We present a simple discussion of the appearance of light-front partons in local field theory.The description in terms of partons provides a dimensional reduction which relates a 2+1 with a 3+1 dimensional theory for example. The possibility for existence of Lorentz symmetry and a connection to the relativistic membrane is described. It is shown how the reconstruction of the full relativistic field theory is possible with a proper treatment of the parton configuration space. Compared with the case of identical particles this involves keeping configurations where the partons are at the same points.
