Analogous Fourier analysis is also carried out. It is verified that energy is transferred locally. We also find that, in terms of wavelet analysis and geometrically partitioned Fourier band average analysis, the contribution of local interactions to the transfer is not negligible compared to that of nonlocal ones. On the other hand, Iinearly partitioned Fourier band average analysis drastically changes the qualitative appearance of transfer process, i.e. the result shows the predominance of nonlocal interactions."}, title = {Local or Nonlocal?
