| Abstract: | In this work, we have considered variable G in flat FRW universe filled with the mixture of dark energy, dark matter and radiation. If there is no interaction between
the three fluids, the deceleration parameter and statefinder parameters have been calculated in terms of dimensionless density
parameters which can be fixed by observational data. Also the interaction between three fluids has been analyzed due to constant
G. The statefinder parameters also calculated in two cases: pressure is constant and pressure is variable. |
