Pointwise slant submanifolds and their warped products in Sasakian manifolds

Abstract: Recently, B.-Y. Chen and O.J. Garay studied pointwise slant submanifolds of almost Hermitian manifolds. In this paper, first we study pointwise slant and pointwise pseudo-slant submanifolds of almost contact metric manifolds and then using this notion, we show that there exist a non-trivial class of warped product pointwise pseudo-slant submanifolds of Sasakian manifolds by giving some useful results, including a characterization.

“…A step forward, Park [12] extended the notion of pointwise slant submanifolds in the setting of AC-metric manifolds. Recently, Uddin and Al-Khalidi [24] modified the definition of pointwise slant submanifolds for ACmetric manifolds. More precisely, a submanifold M of an AC-metric manifold M is referred to as poinwise slant submanifold if ∀Y ∈ T y M such that η ∈ TM the angle θðYÞ between ΨY and T y M − f0g is independent of the choice of nonzero vector field Y ∈ T p M − f0g.…”

Recently, Uddin and Al-Khalidi [25] modified the definition of pointwise slant submanifolds for almost contact metric manifolds. More precisely, a submanifold M of an almost contact metric manifold M is said to be pointwise slant submanifold if for any X ∈ T x M such that η is tangential to M, the angle θðX Þ between Ψ X and T x M − f0g is independent of the choice of non zero vector field X ∈ T p M − f0g.…”

“…where BN and CN are the tangential and normal components of ϕN, respectively. Now, let us recall some basic facts of pointwise slant submanifolds of almost contact manifolds from [15] and [27] before we start to study on our main parts of the present paper.…”
