A geometric inequality for warped product semi-slant submanifolds of nearly cosymplectic manifolds
Siraj Uddin, Abdulqader Mustafa, Bernardine R. Wong +1
Recently, we have shown that there do not exist the warped product semi-slant submanifolds of cosymplectic manifolds [10]. As nearly cosymplectic structure generalizes cosymplectic…
Generalized inequalities on warped product submanifolds in nearly trans-Sasakian manifolds
Abdulqader Mustafa, Siraj Uddin, B. R. Wong
In this paper, we study warped product submanifolds of nearly trans-Sasakian manifolds. The non-existence of the warped product semi-slant submanifolds of the type $N_θ\times{_{f}N…
An optimal inequality on warped product semi-slant submanifolds of nearly Kaehler manifolds
Siraj Uddin, Falleh R. Al-Solamy, V. A. Khan +1
Non-existence of warped product semi-slant submanifolds of Kaehler manifolds was proved in [17], it is interesting to find their existence. In this paper, we prove the existence of…
Classification of totally umbilical slant submanifolds of a Kenmotsu manifold
Siraj Uddin, Zafar Ahsan, A. H. Yaakub
The purpose of this paper is to classify totally umbilical slant submanifolds of a Kenmotsu manifold. We prove that a totally umbilical slant submanifold of a Kenmotsu manifold…
Geometry of warped product semi-slant submanifolds of Kenmotsu manifolds
Siraj Uddin
In this paper, we study semi-slant submanifolds and their warped products in Kenmotsu manifolds. The existence of such warped products in Kenmotsu manifolds is shown by an example…
B.-Y. Chen's inequality for -warped products in a locally conformal Kaehler space form
Siraj Uddin, Khushwant Singh, Fatimah Alghamdi +1
n this paper, we obtain a geometric inequality between the length of the second fundamental form and the length of Lee form in terms of the warping function for a CR-warped product…
