Role of Tachyonic Field in Accelerating Universe in Presence of Perfect Fluid

Understand

Recently tachyonic field has been depicted as dark energy model to represent the present acceleration of the Universe.

• In this paper we have considered mixture of tachyonic fluid with a perfect fluid.
• For this purpose we have considered barotropic fluid and Generalized Chaplygin gas(G.C.G.).
• We have considered a particular form of the scale factor.
