Self-organization without conservation: true or just apparent scale-invariance?
Self-organization without conservation: true or just apparent scale-invariance?
The existence of true scale-invariance in slowly driven models of self-organized criticality without a conservation law, such as forest-fires or earthquake automata, is scrutinized in this paper. By using three different levels of description—(i) a simple mean field, (ii) a more detailed mean-field description in terms of a (self-organized) branching …
