Abstract.
It follows from a theorem of Gromov that the stable systolic category \({\rm cat}_{\rm stsys} M\) of a closed manifold M is bounded from below by \({\rm cl}_{\mathbb{Q}} M\), the rational cup-length of M [Ka07]. We study the inequality in the opposite direction. In particular, combining our results with Gromov’s theorem, we prove the equality \({\rm cat}_{\rm stsys} M = {\rm cl}_{\mathbb{Q}} M\) for simply connected manifolds of dimension ≤ 7.
