Study of a tachyonic field and its statefinder diagnostics in various scenarios of the anisotropic universe

Abstract

In the present work, we have considered N-dimensional Einstein field equations in which 4-dimensional space-time is described by a FRW metric and that of the extra d-dimensions by an Euclidean metric. Considering the universe filled with tachyonic field we have reconstructed the potential V (φ) corresponding to the field reconstructions in an anisotropic universe under Emergent-Power law, Emergent-Intermediate, Emergent-Logamediate andLogamediate-Intermediate scenarios. The statefinder parameters have been investigated in all of the said scenarios.
