Abstract
We study in some detail the field theory formulation in co-ordinate space of the Neveu-Schwarz model for theN-pion amplitude and for theN-pion emission from a single quark line. We then consider the problem of current algebra for the fermion and for the boson case. In particular for the boson case we find a class of axial currents which satisfy the localSU2×SU2 algebra with the isospin currents and the PCAC relation between external real states.
