Abstract : It is well known that critical points of the total scalar curvature functional ${\mathcal S}$ on the space of all smooth Riemannian structures of volume $1$ on a compact manifold $M$ are exactly the Einstein metrics. When the domain of ${\mathcal S}$ is restricted to the space of constant scalar curvature metrics, there has been a conjecture that a critical point is isometric to a standard sphere. In this paper we investigate the relationship between the first Betti number and stable minimal surfaces, and study the analytic properties of stable minimal surfaces in $M$ for $n=3$.
