Positive scalar curvature on foliations

Positive scalar curvature on foliations We generalize classical theorems due to Lichnerowicz and Hitchin on the existence of Riemannian metrics of positive scalar curvature on spin manifolds to the case of foliated spin manifolds As a consequence we show that there is no foliation of positive leafwise scalar curvature on any torus which

TOPOLOGICAL DESCRIPTION OF RIEMANNIAN

is more useful to generalize topological properties of riemannian foliations Another relevant property for this purpose is quasi-efiectiveness which is a generalization to pseudogroups of efiectiveness for group actions In the case of locally connected fo-liated spaces quasi-efiectiveness is equivalent to the quasi-analyticity introduced by
