Query: Decaying magnetohydrodynamics: effects of initial conditions   We study the effects of homogenous and isotropic initial conditions on
decaying Magnetohydrodynamics (MHD). We show that for an initial distribution
of velocity and magnetic field fluctuations, appropriately defined structure
functions decay as power law in time. We also show that for a suitable choice
of initial cross-correlations between velocity and magnetic fields even order
structure functions acquire anomalous scaling in time where as scaling
exponents of the odd order structure functions remain unchanged. We discuss our
results in the context of fully developed MHD turbulence.
