RUDN Waters (IMAGE) RUDN University Caption RUDN University mathematician Masahiro Yamamoto and his colleagues considered the one dimensional fractional diffusion equation for an arbitrary parameter a with a value between 0 and 1. They managed to demonstrate that in the fractional case there is also a continuation theorem, moreover, in the same formulation: if the density and the flux of particles are zero at one boundary point over a time interval, then nothing diffuses.
