Foliations and complemented framed structures on an almost contact metric manifold (Q545472)

The author studies a Riemannian manifold equipped with a generalized quasi-Sasakian (GQS) structure, a structure generalizing the notions of Sasakian, quasi-Sasakian, Kenmotsu, cosymplectic (and other well known) structures. He provides conditions under which a natural foliation and a bundle-like metric on a GQS manifold arise. The paper is closely related to an earlier paper by the author [``Foliations and complemented framed structures'', Bull. Belg. Math. Soc. -- Simon Stevin 17, No.~3, 499--512 (2010; Zbl 1204.53023)].
