Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

The holographic cut-off, in the formalism of generalized holographic dark energy (HDE), is
generalized to depend on L IR= L IR (L p, L˙ p, L¨ p,⋯, L f, L˙ f,⋯, a), where L p and L f are the …

We propose a new four-parameter entropy function that generalizes the Tsallis, Rényi,
Barrow, Sharma-Mittal, Kaniadakis and Loop Quantum Gravity entropies for suitable limits of …

Recently, Barrow argued that quantum-gravitational effects may introduce intricate, fractal
features on the black hole horizon [JD Barrow,, The area of a rough black hole, Phys. Lett. B …

We study the cosmological evolution of a nonflat Friedmann-Robertson-Walker Universe
filled by pressureless dark matter and Barrow holographic dark energy (BHDE). The latter is …

We propose a new five-parameter entropy function that proves to be singular-free during the
entire cosmic evolution of the universe, and at the same time, also generalizes the Tsallis …

We construct Barrow holographic dark energy in the case of nonflat universe. In particular,
considering closed and open spatial geometry we extract the differential equations that …

Kaniadakis statistics is a widespread paradigm to describe complex systems in the
relativistic realm. Recently, gravitational and cosmological scenarios based on Kaniadakis …

In the formalism of generalized holographic dark energy, the infrared cut-off L IR is
generalized to the form, L IR= L IR (L p, L˙ p, L¨ p,⋯, L f, L˙ f, L¨ f,⋯, a, H, H˙, H¨,⋯), where L p …

We report the effects of entropic corrections to the Friedmann equations on the growth of
perturbations in the early stages of the universe. We consider two types of corrections to the …
