Abstract

In this paper we study consistent solutions of spherically symmetric space in metric f (R) gravity theory. Here
we inversely obtain a generic action from metric solutions that describe flat rotation curves in spiral galaxies
without dark matter. Then we show that obtained solutions are in conformity with Tully-Fisher relation and
modified Newtonian dynamics, which are two strong constraints in justification of flat rotation curves in spiral
galaxies.
