Anisotropic magnetohydrodynamic spectral transfer in the diffusion approximation.
A theoretical model of spectral transfer for anisotropic magnetohydrodynamic (MHD) turbulence is introduced, approximating energy transport in wave vector (k) space as a nonlinear diffusion process, extending previous isotropic k -space diffusion theories for hydrodynamics and MHD. This formal closure at the spectral equation level may be useful in space and astrophysical applications.
