TL;DR
This paper reviews nonextensive statistical mechanics and proposes using entropic nonextensivity (q-1) as a simple measure to characterize the complexity of certain systems.
Contribution
It introduces the idea of using entropic nonextensivity as a novel, straightforward metric for system complexity within the framework of nonextensive thermodynamics.
Findings
q-1 can serve as an effective complexity indicator
Nonextensive mechanics offers insights into system behavior
Historical context enriches the understanding of nonextensive concepts
Abstract
An updated review [1] of nonextensive statistical mechanics and thermodynamics is colloquially presented. Quite naturally the possibility emerges for using the value of q-1 (entropic nonextensivity) as a simple and efficient manner to provide, at least for some classes of systems, some characterization of the degree of what is currently referred to as complexity [2]. A few historical digressions are included as well.
