On a Geometric Generalization of Entropy
Problems of Information Transmission, 2003The geometrized entropy is introduced as a generalization of Shannon's entropy and some of its properties are studied.

ON GENERALIZED CUMULATIVE ENTROPIES
Probability in the Engineering and Informational Sciences, 2016In the present paper, we introduce a generalization of the cumulative entropy proposed by Di Crescenzo and Longobardi [8]. This new notion is related to the lower records and the reversed relevation transform. Dynamic version of the newly proposed measure is considered.

Mathematical Notes, 1996
The purpose of this note is to study Renyi entropies from the ergodic theory viewpoint. Applications of the Renyi entropies to dynamical systems seem to have first appeared in the physical literature in order to define chaotic behaviour numerically. Here the authors present an elegant and mathematically rigorous approach to Renyi entropies.

A numerical investigation of the free convection of the Al2O3/water nanofluid was carried out in a square cavity. The cavity was tilted and exposed to a constant horizontal magnetic field. Radiation also occurred in the cavity, and entropy generation was

In this work, the free convection of Al2O3/water nano-fluid in a tilted enclosure is investigated. The enclosure is under a magnetic field. A curved shape fin is placed in the lower part of the enclosure. The fin is at a higher temperature of Th, and the

A generalization of entropy equation: homogeneous entropies
Kybernetika, 1985The general continuous, positively homogeneous (of degree \(\alpha\), \(\alpha >0)\) and symmetric solutions of the equation \[ H(x,y,z)- H(x+y,0,z) =G(x,y) \qquad (x\geq 0, y\geq 0, z\geq 0, xy+yz+zx>0) \] are determined by means of distributions (in the sense of Schwartz). The corresponding homogeneous entropies are defined and characterized.
