On Rényi Permutation Entropy
1Institute of Mathematics, University of Lübeck, D-23562 Lübeck, Germany.
This study explores Rényi permutation entropies, a novel variant of permutation entropy. These entropies, parameterized by q, generalize Shannon entropy and connect to other complexity measures.
Area of Science:
- Complexity Science
- Information Theory
- Nonlinear Dynamics
Background:
- Permutation entropy quantifies system dynamics via ordinal patterns.
- Rényi entropies offer a generalized framework for information quantification.
- Existing literature has explored modifications of permutation entropy.
Purpose of the Study:
- To discuss the concept of Rényi permutation entropies.
- To analyze the dependence on the parameter q.
- To explore connections to established entropy measures.
Main Methods:
- Definition of Rényi permutation entropy based on Rényi entropy.
- Parameterization using the non-negative real number q.
- Comparative analysis with Shannon entropy (q=1).
Main Results:
- Rényi permutation entropy is introduced as a generalization.
- The parameter q controls the entropy measure.
- Connections to Kolmogorov-Sinai entropy and symbolic correlation integral are established.
Conclusions:
- Rényi permutation entropy provides a flexible tool for analyzing complex systems.
- This framework unifies different entropy measures.
- Further research can leverage this concept for deeper insights into system dynamics.

Entropy and the Second Law of Thermodynamics
The relation between entropy and disorder can be illustrated with the example of the phase change of ice to water. In ice, the molecules are located at specific sites giving a solid state, whereas, in a liquid form, these molecules are much freer to move. The molecular arrangement has therefore become more randomized. Although the change in average...
Entropy Change in Reversible Processes
The statement can be further generalized to prove that entropy is a state function. Take a cyclic process between any two points on a p-V diagram.
