Foliations on \(CR\) manifolds
The author performs the study of foliations on (not necessarily embedded) CR-manifolds. He shows that for such a manifold \(M\), there exists a foliation s.t. every leaf is a completely non-integrable CR-submanifold of \(M\) and has the same complex tangent space as \(M\). The existence of the Levi foliation for the abstract case is proved and some of its geometric properties are investigated, thus generalizing some known results for the case of embedded CR-manifolds [see e.g. \textit{M. Freeman}, Proc. Am. Math. Soc. 57, 369-370 (1976; Zbl 0328.32006)].
