Abstract
In this paper, we investigate rank 2 Seiberg–Witten equations which were introduced and studied in Massamba and Thompson (J Geom Phys 56:643–665, 2006). We derive some lower bounds for certain curvature functionals on the space of Riemannian metrics of a smooth compact 4-manifold with non-trivial rank 2 Seiberg–Witten invariants. Existence of Einstein and anti-self-dual metrics on some compact oriented 4-manifolds is also discussed.
