WebTheorem 1.6 ([GL83]). An enlargeable spin manifold does not admit any metric of positive scalar curvature. In this paper, we extend the Gromov-Lawson result as follows. Theorem 1.7. If M is an enlargeable manifold, then no spin foliation of M with Hausdorff homotopy groupoid has a metric of positive scalar curvature.
