ADVECTION OF VECTOR ADMIXTURE BY TURBULENT FLOWS WITH

Using the field theoretic renormalization group and the operator product expansion the struc-ture of the fluctuations of passively advected magnetic field in a given anisotropic stochastic environment is analyzed. Inertial-range anomalous scaling behaviour is studied, and explicit asymptotic expressions for structure functions are determined. The corresponding anomalous exponents are calculated in the first order in a small parameter of the model as functions of the anisotropy parameters. The negativeness of some exponents indicates a complex multifractal structure of the fluctuations of the passively advected magnetic field in such environment. PACS: 47.27.i
