Abstract:
In the first part of the talk, I will present a recent approach to black hole
thermodynamics where the Bekenstein-Hawking entropy is regarded as
a nonextensive Tsallis entropy, and the thermodynamic and stability
properties of the system are obtained via its formal logarithm, the
Rényi entropy function. In the second part, I will introduce a parametric
model for cosmic information entropy in order to consider the problem
of information entanglement between spatially separated but causally
connected regions of the universe.
