Description
The main objective of this article is to study the fractal FRW cosmological model consisting two forms of dark energy. We studied behavior of the universe in a fractal framework using dark energy accommodated in our universe. The solution of field equations are obtained by using Hubble parameter for transit scale factor $ H(z)=\epsilon \left( a^{-\delta}+\lambda\right)$
. We have obtained the best fitting values of the model parameters $\epsilon, \delta$ and $\lambda$ by constraining our model with latest Hubble data sets consisting 57 data points. Finally we perform statefinder diagnosis and observe that obtained model close to standard $\Lambda$CDM model.
