Decoupling of Zero-Modes and Covariance in the Light-Front Formulation   of Supersymmetric Theories
  We show under suitable assumptions that zero-modes decouple from the dynamics of non-zero modes in the light-front formulation of some supersymmetric field theories. The implications for Lorentz invariance are discussed.
