Abstract

The dynamics of world terror and the war in Iraq were studied from different aspects. World terror displays a scaling growth while the rate equations of the civilian and the US-soldier casualties in Iraq both display zero-order chemical kinetics. The fractal dimensions of scattering diagrams were evaluated. Animal diagrams were obtained from scattering diagrams. A similarity/dissimilarity ratio was defined to relate any casualty event to a former one. This ratio implies that the dynamics of civilian casualties in Iraq is very complex. The changes of topological indices of animal diagrams were evaluated with respect to time and the area of the blank zones. The topological index changes linearly with time, and there exists a scaling relation between the topological index and the area of the blank zones in the case of world terror. The area of blank zones in the scattering diagram of US-soldiers decreases with the increase of topological index implying that the dynamics is confined to the scattering diagram. The area keeps almost constant for civilian casualties in Iraq with a jump after some time, and it implies that the dynamics has a growing tendency. There are two self-similarity patterns in the scattering diagram of world terror; one is peak-like and expanding, and the other is triangular and controls the growth. There is only a triangular controlling pattern for the scattering diagram of civilian casualties, and there is no significant self-similarity pattern for the scattering diagram of the US-soldier casualties in Iraq.
