On contact CR-submanifolds of sasakian manifolds [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1983
Recently, K.Yano and M.Kon [5] have introduced the notion of a contact CR-submanifold of a Sasakian manifold which is closely similar to the one of a CR-submanifold of a Kaehlerian manifold defined by A. Bejancu [1].

Quaternion CR-submanifolds of a quaternion Kaehler manifold [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We study the quaternion CR-submanifolds of a quaternion Kaehler manifold. More specifically we study the properties of the canonical structures and the geometry of the canonical foliations by using the Bott connection and the index of a quaternion CR ...

Contact CR Submanifolds [PDF]

open access: yesKodai Mathematical Journal, 1982
Let \(\bar M\) be a (2m+1)-dimensional Sasakian manifold with structure tensors (φ,ξ,η,g). We consider a Riemannian manifold isometrically immersed in \(\bar M\) with induced metric tensor field g.

Homology of contact CR-submanifolds

open access: yesFilomat, 2021
In this paper, homology of a contact CR-submanifold of a real hypersurface, which has naturally almost contact metric structure induced from the complex Euclidean space Cm, is examined. More precisely, nonexistence of stable integral currents on a compact contact CR-submanifold of real hypersurface of canonical complex space form Cm is ...

On warped product bi-slant submanifolds of Kenmotsu manifolds [PDF]

open access: yesArab Journal of Mathematical Sciences, 2021
Chen (2001) initiated the study of CR-warped product submanifolds in Kaehler manifolds and established a general inequality between an intrinsic invariant (the warping function) and an extrinsic invariant (second fundamental form).

Ricci Curvature Inequalities for Skew CR-Warped Product Submanifolds in Complex Space Forms

open access: yesMathematics, 2020
The fundamental goal of this study was to achieve the Ricci curvature inequalities for a skew CR-warped product (SCR W-P) submanifold isometrically immersed in a complex space form (CSF) in the expressions of the squared norm of mean curvature vector and

Submersions of {CR} submanifolds [PDF]

open access: yesTohoku Mathematical Journal, 1987
A real submanifold N of a complex Banach manifold V is called a CR submanifold if \(T^ h=TN\cap J(TN)\) is a complex subbundle of the tangent bundle TV; J being the relevant complex structure. Assume V Kähler, let \(T^{\vee}N\) be the orthogonal complement of \(T^ hN\) in TN, \(T^ nN\) be the normal bundle. Assume that J interchanges \(T^{\vee}N\) and \
