Abstract

We collect the main results obtained along this Ph.D. thesis: \Non-perturbative methods in non-linear eld theories and their supersymmetric extensions". The rst original presentation for K eld theories is performed in chapter 7. We proposed a simpler supersymmetric extension of such theories. With this extension it is easy to calculate supersymmetric charges, and therefore all the supersymmetric algebra is found. Nevertheless, in the last section we demonstrate that with this oversimpli ed scheme of supersymmetrization the model contains ghosts.
