Abstract
We consider the Riemannian functional \(\mathcal {R}_{p}(g)={\int }_{M}|R(g)|^{p}dv_{g}\) defined on the space of Riemannian metrics with unit volume on a closed smooth manifold M where R(g) and dv g denote the corresponding Riemannian curvature tensor and volume form and p ∈ (0, ∞). First we prove that the Riemannian metrics with non-zero constant sectional curvature are strictly stable for \(\mathcal {R}_{p}\) for certain values of p. Then we conclude that they are strict local minimizers for \(\mathcal {R}_{p}\) for those values of p. Finally generalizing this result we prove that product of space forms of same type and dimension are strict local minimizer for \(\mathcal {R}_{p}\) for certain values of p.
