Inflation based on the Tsallis entropy [PDF]

The European Physical Journal C, 2023
AbstractWe study the inflationary scenario in the Tsallis entropy-based cosmology. The Friedmann equations in this setup can be derived by using the first law of thermodynamics. To derive the relations of the power spectra of the scalar and tensor perturbations in this setup, we reconstruct an f(R) gravity model which is thermodynamically equivalent to

Tsallis Entropy, Likelihood, and the Robust Seismic Inversion. [PDF]

Entropy (Basel), 2020
The nonextensive statistical mechanics proposed by Tsallis have been successfully used to model and analyze many complex phenomena. Here, we study the role of the generalized Tsallis statistics on the inverse problem theory.

Tsallis Entropy and the Transition to Scaling in Fragmentation [PDF]

Entropy, 2000
By using the maximum entropy principle with Tsallis entropy we obtain a fragment size distribution function which undergoes a transition to scaling. This distribution function reduces to those obtained by other authors using Shannon entropy. The treatment is easily generalisable to any process of fractioning with suitable constraints.

On Uniqueness Theorems for Tsallis Entropy and Tsallis Relative Entropy [PDF]

IEEE Transactions on Information Theory, 2005
The uniqueness theorem for Tsallis entropy was presented in {\it H.Suyari, IEEE Trans. Inform. Theory, Vol.50, pp.1783-1787 (2004)} by introducing the generalized Shannon-Khinchin's axiom. In the present paper, this result is generalized and simplified as follows: {\it Generalization}: The uniqueness theorem for Tsallis relative entropy is shown by ...

Tsallis entropy of uncertain random variables and its application

Soft Computing, 2021
Tsallis entropy is a flexible extension of Shanon (logarithm) entropy. Since entropy measures indeterminacy of an uncertain random variable, this paper proposes the concept of partial Tsallis entropy for uncertain random variables as a flexible devise in

Some Properties of Fractal Tsallis Entropy [PDF]

Fractal and Fractional, 2023
We introduce fractal Tsallis entropy and show that it satisfies Shannon–Khinchin axioms. Analogously to Tsallis divergence (or Tsallis relative entropy, according to some authors), fractal Tsallis divergence is defined and some properties of it are ...
