Abstract: | C∞-foliations of codimension 1 on compact Riemannian 3-manifolds are studied. New classes of foliations, namely hyperbolic,
elliptic, and parabolic foliations, are considered. Examples of such foliations are presented. In particular, aC∞-metric of nonnegative sectional curvature onS
3 such that the Reeb foliation is parabolic with respect to this metric is constructed. Analytic 3-manifolds with sectional
curvature of constant sign admitting parabolic foliations are classified.
