Warped Product Submanifolds of Riemannian Product Manifolds
Abstract and Applied Analysis, 2012 We study warped product of the type Nθ×fNT and Nθ×fN⊥, where Nθ, NT, and N⊥ are proper slant, invariant, and anti-invariant submanifolds, respectively, and we prove some basic results and finally obtain some inequalities for squared norm of second ...

Anti-invariant submanifolds of almost contact metric manifolds
Mathematische Annalen, 1977 Let M be a submanifold of a Riemannian manifold ]fir and P an endomorphism of the tangent bundle T M of M. If F T x M 3_T ,M for each point x¢ M, we say that M is an anti-invariant submanifold of M under F. If P is an almost complex structure, then such M are usually called totally real submanifolds and have been studied by various authors [1, 3, 5-7].

Invariant, anti-invariant and slant submanifolds of a metallic manifold
Novi Sad Journal of Mathematics, 2018 Summary: Properties of invariant, anti-invariant and slant isometrically immersed submanifolds of metallic Riemannian manifolds are given with a special view towards the induced \(\Sigma \)-structure. Examples of such metallic manifolds are also given.

Skew semi-invariant submanifolds of generalized quasi-Sasakian manifolds
Karpatsʹkì Matematičnì Publìkacìï, 2018 In the present paper, we study a new class of submanifolds of a generalized Quasi-Sasakian manifold, called skew semi-invariant submanifold. We obtain integrability conditions of the distributions on a skew semi-invariant submanifold and also find the ...

Isometric immersions into three‐dimensional unimodular metric Lie groups
Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.Abstract We study isometric immersions of surfaces into simply connected three‐dimensional unimodular Lie groups endowed with either Riemannian or Lorentzian left‐invariant metrics, assuming that Milnor's operator is diagonalizable in the Lorentzian case.

Totally real submanifolds of the nearly kaehler 6-sphere [PDF]
, 1997 Totally real 3-dimensiunal submanifolds of the nearly Kaehler 6-sphere are the main topic of this thesis. Having introduced preliminaries on the theory of complex and almost complex manifolds, the nearly Kaehler structure of S(^6) and the non existence ...

A Note on Invariant Submanifolds of Metallic Riemannian Manifolds
, 2023 The goal of this paper is to examine invariant submanifolds in metallic Riemannian manifolds with the help of induced structures on them by the metallic Riemannian structure of the ambient manifold.

A Classification of a Totally Umbilical Slant Submanifold of Cosymplectic Manifolds
Abstract and Applied Analysis, 2012 We study slant submanifolds of a cosymplectic manifold. It is shown that a totally umbilical slant submanifold 𝑀 of a cosymplectic manifold 𝑀 is either an anti-invariant submanifold or a 1−dimensional submanifold.

Identifiability of points and rigidity of hypergraphs under algebraic constraints
Journal of the London Mathematical Society, Volume 114, Issue 1, July 2026.Abstract The identifiability problem arises naturally in a number of contexts in mathematics and computer science. Specific instances include local or global rigidity of graphs and unique completability of partially‐filled tensors subject to rank conditions.
