Abstract

In this thesis, we exhibit the results of the study made for the non linear models with O(N) symmetry, bosonic or supersymmetric as well as with the addition the topological Wess-Zumino term (WZNW theory). We found their non-local conserved charges and the structure of the corresponding c1assical algebras of Dirac brackets, using a graphical method that we created to make these calculations. (AU)
