Positive Scalar Curvature on Foliations: Long Neck Problem

We prove estimates for Gromov’s Long Neck Foliated Conjecture in the spin cases, which involves leafwise scalar curvature. The same methods yield a quantitative version of a theorem of Su–Wang–Zhang and a Llarull-type theorem for closed foliated manifolds. A refinement, which involves mean curvature and partially generalizes a theorem of Cecchini–Zeidler, is also obtained.
