چکیده
In this paper, we introduce a new class of contact pseudo framed (CPF)-manifolds M,g,f,λ,ξ by real tensor field id="M2">f type id="M3">1,1 , function id="M4">λ such that id="M5">f3=λ2f where id="M6">ξ is its characteristic vector field. We prove in our main Theorem 2 id="M7">M admits closed 2-form id="M8">Ω if id="M9">λ constant. 1976, Blair proved the id="M10">ξ normal manifold Killing. Contrary to this, have shown that, general, id="M11">ξ CPF-manifold non-Killing. also established link CPF-hypersurfaces with curvature, affine, conformal collineations symmetries, and almost Ricci soliton manifolds, supported three applications. odd-dimensional construct several examples even- semi-Riemannian lightlike CPF-manifolds propose two problems for further consideration.

Curvature of a class of indefinite globally framed f-manifolds
We present a compared analysis of some properties of indefinite almost S-manifolds and indefinite S-manifolds. We give some characterizations in terms of the Levi-Civita connection and of the characteristic vector fields. We study the sectional and φ-sectional curvature of indefinite almost S-manifolds and state an expression of the curvature tensor field for the indefinite S-space forms. We an...

متن کاملSemi-slant Pseudo-riemannian Submersions from Indefinite Almost Contact 3-structure Manifolds onto Pseudo-riemannian Manifolds
In this paper, we introduce the notion of a semi-slant pseudoRiemannian submersion from an indefinite almost contact 3-structure manifold onto a pseudo-Riemannian manifold. We investigate the geometry of foliations determined by horizontal and vertical distributions and provide a non-trivial example. We also find a necessary and sufficient condition for a semi-slant submersion to be totally geo...
متن کاملFramed Knot Contact Homology
We extend knot contact homology to a theory over the ring Z[λ±1, μ±1], with the invariant given topologically and combinatorially. The improved invariant, which is defined for framed knots in S and can be generalized to knots in arbitrary manifolds, distinguishes the unknot and can distinguish mutants. It contains the Alexander polynomial and naturally produces a two-variable polynomial knot in...
متن کاملFramed Knots in 3-manifolds
For a fixed isotopy type K of unframed knots in S there are infinitely many isotopy classes of framed knots that correspond to K when we forget the framing. We show that the same fact is true for all the isotopy types of unframed knots in a closed oriented 3-manifold M , provided that M 6= (S × S)#M . On the other hand for any M = (S × S)#M ′ we construct examples of isotopy classes of unframed...
