Nonsingular solution with anisotropic fluid in mini bang cosmology

Abstract

In this work, we study cosmological evolution in the mini creation event with anisotropic fluid under the Bianchi-I spacetime. After providing the basic mathematical formalism of the model, we find out the exact solutions in its particular form to the field equations. In order to get physical validity, we have presented elaborate discussions on the graphical results, especially nonsingular behaviour of the model. It is shown that the model under mini bang can successfully exhibit several interesting cosmological features which have specific signatures to tally with the observational evidences.

Multiple fluid theory of cosmic evolution and its thermodynamic analysis

“…From [68][69] we'll discuss modified structure of 𝑓(𝑅, 𝑇) = 𝑅 + 2𝑓(𝑇) = 𝑅 + 2𝜆𝑇. Assuming 𝑓(𝑇) = 𝜆𝑇.…”

“…Thus, the expansion has been described physically. [57][58][59][60][61][62][63][64][65][66][67][68][69][70][71][72]…”

“…On the other hand, in compact bodies the interaction can provide additional pressures to establish equilibrium. [62][63][64][65][66][67][68][69][70][71][72][73][74][75][76][77][78][79][80] This paper has been prepared as follows.…”
