Abstract
We conjecture general criteria for a dual or parton theory to have a Goldstone-Nambu boson and prove the consistency of the criteria by demonstrating an exactly solvable model. The amplitudes constructed from this model satisfy all soft-pion theorems or Adler zero conditions. A second unsolvable model based on a ferromagnetic state of the spins of the parton distribution is shown to satisfy the general criteria conjectured on the basis of the first model.
