Jin, Dae Ho Geometry of lightlike hypersurfaces of an indefinite cosymplectic manifold. (English) Zbl 1243.53084 Commun. Korean Math. Soc. 27, No. 1, 185-195 (2012). The author studies the geometry of light-like hypersurfaces \(M\) of an indefinite cosymplectic manifold \(\overline M\) such that either (1) the characteristic vector field \(\zeta\) of \(\overline M\) belongs to the screen distribution \(S\) of \(M\) or (2) \(\zeta\) belongs to the orthogonal complement \(S^{\perp}\) of \(S\) in \(T\overline M\).
