Study of Tachyonic Field and its statefinder diagnostics in Various
Scenarios of The Anisotropic Universe
   [PDF]

Chayan Ranjit, Surajit Chattopadhyay
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 $V(\phi)$ corresponding to the field reconstructions in an anisotropic universe under \emph{Emergent-Power law}, \emph{Emergent-Intermediate}, \emph{Emergent-Logamediate}and \emph{Logamediate-Intermediate} scenarios. The statefinder parameters have been investigated in all of the said scenarios.
