Outline of Final Research Achievements |
Studying various fractal systems to understand structure formation mechanisms and dynamics in a unified manner, we have obtained the following results. (1) Based on the fact that an order parameter at criticality is distributed with the generalized Gumbel distribution function, the distribution of the fractal dimension characterizing spatial profile of the local order parameter near the critical point generally obeys a triple exponential function, (2) the distribution of the fractal dimension of coastline formed by a self-organized critical (SOC) dynamics obeys the triple exponential function, (3) scale-free networks are robust against cascading failures by temporally fluctuating loads, (4) an SOC model to explain the spontaneous formation of fractal complex networks has been constructed.
