It is not possible to compute gauge non-singlet matrix elements. In the present language, constraints from higher conservation laws determine the bound state solution. An alternative derivation is also presented. © 1988.281-284engBound state solution of the grassmannian nonlinear sigma model with fermionsArtigo10.1016/0370-2693(88)91506-7Acesso restrito2-s2.0-38249030292
