A non-singular generalized entropy and its implications on bounce cosmology
Sergei D. Odintsov, Tanmoy Paul
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 Tsal…
Modified cosmology from the thermodynamics of apparent horizon
Shin'ichi Nojiri, Sergei D. Odintsov, Tanmoy Paul
In the realm of the Bekenstein-Hawking entropy, the thermodynamics of apparent horizon bridges with the usual FLRW (Friedmann-Lemaître-Robertson-Walker) equation only for a special…
On property- and relative Chebyshev centers in Banach spaces-II
Syamantak Das, Tanmoy Paul
We continue to study (strong) property- in Banach spaces. As discussed by Pai \& Nowroji in [{\it On restricted centers of sets}, J. Approx. Theory, {\bf 66}(2), 170--189 (1…
Viable requirements of curvature coupling helical magnetogenesis scenario
Tanmoy Paul
In the present work, we examine the following points in the context of the recently proposed curvature coupling helical magnetogenesis scenario \cite{Bamba:2021wyx} -- (1) whether…
Bounce universe with finite-time singularity
Sergei D. Odintsov, Tanmoy Paul
This work explains how the presence of a Type-IV singularity (a mild singularity) can influence the dynamics of a bouncing universe. In particular, we examine bounce cosmology that…
Early and late universe holographic cosmology from a new generalized entropy
Shin'ichi Nojiri, Sergei D. Odintsov, Tanmoy Paul
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 th…
Aspects of non-singular bounce in modified gravity theories
Indrani Banerjee, Tanmoy Paul, Soumitra SenGupta
Scenario of a bouncing universe is one of the most active area of research to arrive at singularity free cosmological models. Different proposals have been suggested to avoid the s…
Towards a smooth unification from an ekpyrotic bounce to the dark energy era
Shin'ichi Nojiri, Sergei D. Odintsov, Tanmoy Paul
In the context of a ghost free model, we present a non-singular cosmological scenario in which the universe initially contracts through an ekpyrotic phase having…
Uniqueness of Hahn--Banach extensions and some of its variants
Soumitra Daptari, Tanmoy Paul
In this study, we analyze the various strengthening and weakening of the uniqueness of the Hahn--Banach extension. In addition, we consider the case in which is an ideal of …
Ekpyrotic bounce driven by Kalb-Ramond field
Tanmoy Paul, Soumitra SenGupta
We propose an ekpyrotic bounce scenario driven by a second rank antisymmetric Kalb-Ramond field, where the universe initially contracts through an ekpyrotic stage having a non-sing…
