Description

Quantum theory and gravity bring distinct questions about entropy into view. Topics include generalized information measures, Tsallis and Rényi entropies, group entropies, horizon thermodynamics, holography and cosmological tests. Routes to extensivity through generalized variables, formal logarithms or additional work terms will be compared.

Discussion focus: Distinguishing thermodynamic consistency from quantum-information questions, and identifying theoretical or observational tests of alternative descriptions.
