Early and late universe holographic cosmology from a new generalized entropy
Physics Letters B, 2022 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 the parameters.

Inflationary universe in the presence of a minimal measurable length
, 2017 In this paper, we will study the effect of having a minimum measurable length on inflationary cosmology. We will analyze the inflationary cosmology in the Jacobson approach.

Constraining auto-interaction terms in α-attractor supergravity models of inflation [PDF]
, 2017 The inflationary mechanism has become the paradigm of modern cosmology over the last thirty years. However, there are several aspects of inflationary physics that are still to be addressed, like the shape of the inflationary potential.

Hybrid Loop Quantum Cosmology: An Overview
Frontiers in Astronomy and Space Sciences, 2021 Loop Quantum Gravity is a nonperturbative and background independent program for the quantization of General Relativity. Its underlying formalism has been applied successfully to the study of cosmological spacetimes, both to test the principles and ...

Inflationary cosmology in modified gravity theories
, 2015 We review inflationary cosmology in modified gravity such as $R^2$ gravity with its extensions in order to generalize the Starobinsky inflation model. In particular, we explore inflation realized by three kinds of effects: modification of gravity, the ...

The method of generating functions in exact scalar field inflationary cosmology
European Physical Journal C: Particles and Fields, 2018 The construction of exact solutions in scalar field inflationary cosmology is of growing interest. In this work, we review the results which have been obtained with the help of one of the most effective methods, viz., the method of generating functions ...

Inflation and Fractional Quantum Cosmology
Fractal and Fractional, 2022 The Wheeler–DeWitt equation for a flat and compact Friedmann–Lemaître–Robertson–Walker cosmology at the pre-inflation epoch is studied in the contexts of the standard and fractional quantum cosmology.

String cosmology versus standard and inflationary cosmology
, 2000 This paper presents a review of the basic, model-independent differences between the pre-big bang scenario, arising naturally in a string cosmology context, and the standard inflationary scenario.
