Co-authors	Sajid Ali
Abstract	The Noether symmetries with gauge term are studied for the $f(R)$ cosmological model. By utilization of the Noether Symmetry approach, we obtain some exact forms of $f(R)$ for which such symmetries exist. Further we obtain a time-varying invariant for the Lagrangian despite the fact that it does not depends on time explicitly. The stability analysis of the obtained forms of $f(R)$ is also given.
