Mikhael Gromov and Blaine Lawson, in their classic paper [1980], use Dirac operators with coefficients in appropriate bundles and associated topological invariants to investigate whether or not a given compact nonsimply connected manifold can support a metric of positive scalar curvature. In this appendix we consider the analogous problem for foliated spaces. We use appropriate tangen-tial Dirac operators to investigate the existence of a tangential Riemannian met-ric with positive scalar curvature along the leaves of a compact foliated space. Gromov and Lawson use the Â-genus and the Atiyah–Singer index theorem; we shall use the tangential Â-genus and the Connes index theorem.
