Interaction between Generalized Varying Chaplygin gas and Tachyonic Fluid

Abstract

We consider a mixture of varying Generalized Chaplyagin gas [1] interacting with a Tachyonic fluid in framework of GR. We suppose, that a Tachyonic fluid and Generalized Chaplyagin gas was separated somehow from Darkness of the Universe. Remaining darkness will be described by ${\omega }_X$ and we will have not any other information. We also suppose, that varying Generalized Chaplyagin gas under consideration was appeared due to interaction between remaining Darkness and Generalized Chaplyagin gas. At the same time we assume, that our Tachonic fluid does not fell remaining Darkness. In this letter we investigate graphically the potential $V(\varphi )$ of the Tachyonic fluid and ${\omega }_{tot}$ of the mixture. Interaction between components taken to be sign-changeable, occurring thanks to imposing of deceleration parameter into expression of interaction term [2],[3].
