Foliation of manifold
Webclosed three-manifold admits a one dimensional foliation; for example the three-sphere admits a foliation by round circles (Hopf) and by smooth lines [4]. Epstein, [3], showed that every foliation by circles is a Seifert bration, and this class of manifolds has been extensively studied. A manifold which bers over the circle WebOct 4, 2016 · For a compact complex manifold, we introduce holomorphic foliations associated with certain abelian subgroups of the automorphism group. If there exists a transverse Kähler structure on such a foliation, then we obtain a nice differential graded algebra which is quasi-isomorphic to the de Rham complex and a nice differential bi …

WebFoliations are useful because they can give information about the topological structure of the manifold. For example a non-singular foliation on a 2-manifold M implies that M is the torus or the Klein bottle. A special case of a foliation is a non-singular flow, which serves as model for some physical systems. Share Cite Follow WebDec 1, 2024 · Vaisman manifolds bear a holomorphic foliation of complex dimension 1, generated by the Lee and anti-Lee fields θ ♯ and J θ ♯, usually called the canonical foliation. It is locally Euclidean and transversally Kähler. Unlike Kähler structures, LCK structures are not stable under small deformations ( [1]).
