The canonical lamination calibrated by a cohomology class
Abstract
Let $M$ be a closed oriented Riemannian manifold of dimension $2 \leq d \leq 7$, and let $ρ\in H^{d - 1}(M, \mathbb R)$ have unit norm. We construct a lamination $λ_ρ$ whose leaves are exactly the minimal hypersurfaces which are calibrated by every calibration in $ρ$. The geometry of $λ_ρ$ is closely related to the the geometry of the unit ball of the stable norm on $H_{d - 1}(M, \mathbb R)$, and so we deduce several results constraining the geometry of the stable norm ball in terms of the topology of $M$. These results establish a close analogy between the stable norm on $H_{d - 1}(M, \mathbb R)$ and the earthquake norm on the tangent space to Teichmüller space.
