Vanishing Homology of Warped Product Submanifolds in Complex Space Forms and Applications
Mathematics, 2022 In this paper, we prove the nonexistence of stable integral currents in compact oriented warped product pointwise semi-slant submanifold Mn of a complex space form M˜(4ϵ) under extrinsic conditions which involve the Laplacian, the squared norm gradient ...

Slant and Semi-Slant Submanifolds in Metallic Riemannian Manifolds
Journal of Function Spaces, 2018 The aim of our paper is to focus on some properties of slant and semi-slant submanifolds of metallic Riemannian manifolds. We give some characterizations for submanifolds to be slant or semi-slant submanifolds in metallic or Golden Riemannian manifolds and we obtain integrability conditions for the distributions involved in the semi-slant submanifolds ...

International Journal of Mathematics and Mathematical Sciences, 2005 We establish inequalities between the Ricci curvature and the squared mean curvature, and also between the k-Ricci curvature and the scalar curvature for a slant, semi-slant, and bi-slant submanifold in a locally conformal almost cosymplectic manifold ...

Slant Submanifolds in Complex Euclidean Spaces
Tokyo Journal of Mathematics, 1991 An immersion of a differentiable manifold into an almost Hermitian manifold is called a slant immersion if it has constant Wirtinger angle. The authors prove that every slant immersion of a compact manifold into complex Euclidean space is totally real.

SEMI-SLANT SUBMANIFOLDS OF T-MANIFOLDS
Demonstratio Mathematica, 2006 \(T\)--manifolds are a generalization of cosymplectic manifolds whose study was introduced by \textit{D. E. Blair} [J. Differ. Geom. 4, 155--167 (1970; Zbl 0202.20903)]. Semi-slant submanifolds are a generalization of CR-submanifolds. As indicated by the title of this paper, the authors investigate semi-slant submanifolds of a \(T\)--manifold.

Geometric Mechanics on Warped Product Semi-Slant Submanifold of Generalized Complex Space Forms
Advances in Mathematical Physics, 2021 In this study, we develop a general inequality for warped product semi-slant submanifolds of type Mn=NTn1×fNϑn2 in a nearly Kaehler manifold and generalized complex space forms using the Gauss equation instead of the Codazzi equation.

Geometry of CR-Slant Warped Products in Nearly Kaehler Manifolds
Mathematics, 2023 Recently, we studied CR-slant warped products B1×fM⊥, where B1=MT×Mθ is the Riemannian product of holomorphic and proper slant submanifolds and M⊥ is a totally real submanifold in a nearly Kaehler manifold. In the continuation, in this paper, we study B2×
