The warped product N< sub> 1×< sub> f N< sub> 2 of two Riemannian manifolds (N< sub>
1, g< sub> 1) and (N< sub> 2, g< sub> 2) is the product manifold N< sub> 1× N< sub> 2 …

The famous Nash embedding theorem was aimed for in the hope that if Riemannian
manifolds could be regarded as Riemannian submanifolds, this would then yield the …

In this paper, some relations among the second fundamental form which is an extrinsic
invariant, Laplacian of the warping function and constant sectional curvature of a warped …

The present paper deals with the study of Fischer-Marsden conjecture on a Kenmotsu
manifold. It is proved that if a Kenmotsu metric satisfies 𝔏* g (λ)= 0 on a (2n+ 1)-dimensional …

In this paper, we establish a sharp inequality for the squared norm of the second
fundamental form of bi-warped product submanifolds of Kenmotsu manifolds. The equality …

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 …

In the present paper, we show the existence of warped product semi-slant submanifolds in a
Kenmotsu manifold by an example. We locally characterize the warped product semi-slant …
