| Abstract: | The critical dynamics of an-component order parameter of anO(n)-symmetric system is analyzed with a Gell'Mann-Low-type renormalization group equation ind=4– dimensions. Dynamical scaling holds forn>3/2+O(). Besides the dynamical exponentz=d/2 the correction exponents to order are found. To the same order the shape function of the dynamical order parameter correlation function is calculated which exhibits fluctuation induced peaks forn 3 and extrapolated tod=3. |
