TWO-DIMENSIONAL SELF-ORGANIZED CRITICAL SANDPILE MODELS WITH ANISOTROPIC DYNAMICS OF THE ACTIVITY PROPAGATION

We numerically and analytically investigate two self-organized critical sandpile models with anisotropic dynamics of the activity propagation – Dhar–Ramaswamy and discrete Feder–Feder models. The full set of critical indices for these models is theoretically
