| Research Abstract |
The results are summarized as follows : 1) We have provided the theoretical basis, according to fluid mechanics, on the relationship between fractal dimensions of aggregates and sedimentation velocity. 2) We have theoretically presented the probability distribution function of the fractal dimension characterizing critical fractal systems. 3) We have demonstrated that there holds the dynamic scaling law in inelastic neutron scattering data for anti-ferromagnetic percolating systems. 4) We have clarified the relation between the fractal and the small-world properties of complex network systems.
