Abstract: (Elsevier B.V.)
A block-spin renormalization group analysis is made for the two-dimensional nonlinear O(N) sigma model. The correlation function on the renormalized trajectory for a renormalization group transformation is explicitly obtained near the non-trivial fixed point by perturbation theory. An improved action is obtained in such a way that it is closest to the renormalized trajectory.- FIELD THEORETICAL MODEL: SIGMA
