Complex system

In mathematics, a complex system is a model with with emergent properties.

Description

A complex system is a system that exhibits some (and possibly all) of the following characteristics:

• Feedback loops
• Some degree of spontaneous order
• Robustness of the order
• Emergent organization
• Numerosity
• Hierarchical organization

A complex system can be also viewed as a system composed on many components which may interact with each other.

Networks

In many cases it is useful to represent such a system as a network where the nodes represent the components and the links their interactions.

Examples

Examples of complex systems are Earth's global climate, the human brain, social organization, an ecosystem, a living cell, and ultimately the entire universe.
