A System of Billiard and Its Application to Information-Theoretic Entropy

  title={A System of Billiard and Its Application to Information-Theoretic Entropy},
  author={Supriyo Dutta and Partha Guha},
In this article, we define an information-theoretic entropy based on the Ihara zeta function of a graph which is called the Ihara entropy. A dynamical system consists of a billiard ball and a set of reflectors correspond to a combinatorial graph. The reflectors are represented by the vertices of the graph. Movement of the billiard ball between two reflectors is represented by the edges. The prime cycles of this graph generate the bi-infinite sequences of the corresponding symbolic dynamical…

An analytic technique is proposed, which allows to generate many new examples of entropic functionals generalizing the standard Boltzmann–Gibbs entropy. Our approach is based on the existence of a

A Mathematical Theory of Communication
It is proved that the authors can get some positive data rate that has the same small error probability and also there is an upper bound of the data rate, which means they cannot achieve the data rates with any encoding scheme that has small enough error probability over the upper bound.
