| Research Abstract |
It is a common feature of some physical systems consisting of a large number of coupled systems that a cascade of energy flow from large to small scales generates a scaling behavior, namely power-law behavior of some observable. Scaling is found in a wide range of systems, from geophysical to biological. A typical example is seismicity that is characterized by an energy transfer through a hierarchy structure. One of recent research is to apply this idea to explain the observed scaling laws. In this study, we proposed the general framework of scaling with many variables and its method that exhibit self-similar properties. The commonly used dynamically driven fractal method is useful to analyze the scale invariance of the spatiotemporal structures produced by the operation of the updating algorithm. This method integrates the model in space and time in the analysis of the effect of coarse graining on the dynamics to produce the set of scaling equations from which various characteristic exponents are obtained.
