Abstract

In the present research article, we have studied the flat FRW space time with domain wall and holographic dark energy in the context of $f(Q)$ theory of gravity. The exact solutions of the field equations are obtained using two different forms of varying deceleration parameters: (i) $q=-b(t)-1$ and (ii) $q=-lt+m-1$. It is observed that the universe is accelerating and expanding. Furthermore, we have also discussed some physical parameters of the investigated model.
