In this article, we derive Chen's inequalities involving Chen's δ-invariant δ M, Riemannian
invariant δ (m 1,⋯, mk), Ricci curvature, Riemannian invariant Θ k (2≤ k≤ m), the scalar …

The present paper aims to deliberate the geometric composition of a perfect fluid spacetime
with torse-forming vector field ξ in connection with conformal Ricci–Yamabe metric and …

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 …

It is known from [K. Yano and M. Kon, Structures on Manifolds (World Scientific, 1984)] that
the integration of the Laplacian of a smooth function defined on a compact orientable …

The goal of this paper is to construct a fundamental theorem for the Ricci curvature
inequality via partially minimal isometric warped product immersions into an m-dimensional …

We introduce and study quasi hemi-slant submanifolds of almost contact metric manifolds
(especially, cosymplectic manifolds) and validate its existence by providing some non-trivial …

There are two types of warped product pseudo-slant submanifolds, M 𝜃× f M⊥ and M⊥× f M
𝜃, in a nearly Kaehler manifold. We derive an optimization for an extrinsic invariant, the …

In this study, we develop a general inequality for warped product semi‐slant submanifolds of
type M n= NT n 1× f N ϑ n 2 in a nearly Kaehler manifold and generalized complex space …

The warped product $ N_1\times_f N_2 $ of two Riemannian manifolds $(N_1, g_1) $ and
$(N_2, g_2) $ is the product manifold $ N_1\times N_2 $ equipped with the warped product …
