Abstract: (FIZ Karlsruhe)

In this research, we have studied behaviours of quark matter and strange quark matter which exist in f(R) gravity in presence of Bianchi type universe. In order to obtain a deterministic solution, we have considered the scale factor which is a combination of two factors: the one is the usual power law ex pansion and the second one is an exponential function. We investigate exact f(R) functions for Bianchi V as the contribution of strange quark and quark matter. Effect of the curvature function f(R) is also observed on dynamical parameters. As per the observation both the pressure and density depend on f(R) gravity and the bag constant. Hence both pq and ρq remain positive. Then ρsq→∞ as t→0, and ρsq→3Bc as t→∞. The statefinder parameters r,s converge 1,0 in the distant future and found that our model aligns with the ΛCDM model both at present and in the future. Finally we discussed our physical solutions.
