The Evolution of Complexity - Abstracts. In spite of this, no universally accepted definition of chaos does exist. In this work we consider three different environments in which the notion of chaos arises, e.g., mathematics, physics, and computer science, and discuss similarities and dissimilarities in the corresponding definitions. The set of properties f must satisfy to be chaotic is not uniquely defined.
Transitivity is a widely accepted feature of chaos.
Another feature of chaos is the denseness of the periodic orbits. The notion of chaos captures the concept of non-measurability. More formally, let d be a distance on X . Delta is called sensitivity constant. Note that expansiveness is stronger than sensitivity.
