A novel cosmic framework of interdependent dark matter and Holographic Dark Energy within the Bianchi type-V universe

We study the anisotropic and homogeneous Bianchi type-V Universe with holographic dark energy (HDE) and interacting dark matter (DM). The solution for the field equations have been obtained for a certain form of the deceleration parameter. As for $\mathrm{\Lambda }$CDM, we show that the coincidence problem disappears for a specific choice of the dark matter-holographic dark energy interaction. In this study, the observational data combination of OHD and JLA (Yu et al., Astrophys. J. 856 (2018) 3), where $q_0$ = $-0.52$ and $H_0$ = $69.2$, have been taken into consideration. We also found that the anisotropy of the expansion achieves isotropy after some finite time. We have also explained the physical and geometrical aspects of the model. The physical acceptability and stability of the model have been examined.
