abstract = "The form E ( k , t ) ≃ C m k m in the limit as k → 0 and where C m is independent of k is examined under the assumption that the turbulence is homogeneous and the three-dimensional energy spectrum function is continuous. By using fractional derivatives together with the integrals that relate E ( k , t ) to moments of the two-point correlation functions, it is possible to show that m has to be an even integer. Thus fractional and odd powers are not possible in an infinite domain. "
