Abstract
A derivation in variable dimension of the scaling laws for mixed third -order longitudinal structure and correlation functions for incompress ible magnetized hows is given for arbitrary correlation between the ve locity and magnetic field with full isotropy, homogeneity, and incompr essibility assumed. When close to; equipartition between kinetic and m agnetic energy, the scaling relations involve only structure functions in a manner similar to the ''4/5 law'' of Kolmogorov.
