Abstract
We present a new calculation of the critical exponents of the -vector model through field-theoretical methods. The coefficients of the renormalization functions of the theory are expanded in powers of the coupling constant. Asymptotic estimates of large order of perturbation series are used to transform the divergent perturbation series into a convergent one. As a consequence, new and more precise values of critical exponents are obtained.
