Some submanifolds of generalized Kenmotsu manifolds
Gulf Journal of Mathematics, 2022 In this paper, invariant submanifolds of a generalized Kenmotsu manifold are studied and given some properties. An example is constructed for an invariant submanifold of a generalized Kenmotsu manifold. In addition, integrabilities of invariant distribution is investigated, and some theorems are given related to curvature tensor and the second ...

Generating Forms of Lagrangian Submanifolds [PDF]
Indiana University Mathematics Journal, 1972 A Lagrangian submanifold of a symplectic manifold is a submanifold for which the restriction of the symplectic form vanishes, and which in addition satisfies certain maximality conditions. Special symplectic manifolds are manifolds isomorphic to cotangent bundles.

Biharmonic submanifolds of generalized space forms [PDF]
Differential Geometry and its Applications, 2017 We consider biharmonic submanifolds in both generalized complex and Sasakian space forms. After giving the biharmonicity conditions for submanifolds in these spaces, we study different particular cases for which we obtain curvature estimates. We consider curves, complex and Lagrangian surfaces and hypersurfaces for the generalized complex space form as

GENERIC SUBMANIFOLDS OF QUASI-SASAKIAN MANIFOLDS [PDF]
Demonstratio Mathematica, 2004 The authors study the integrability of the distributions on a generic submanifold of a quasi-Sasakian manifold. The existence of some foliations on a generic submanifold is shown to be equivalent with certain conditions on its second fundamental form and on a tensor field of type \((1,1)\) that has been introduced by Kanemaki for a characterization of ...

Global flow structure and exact formal transseries of the Gubser flow in kinetic theory
Journal of High Energy Physics, 2020 In this work we introduce the generic conditions for the existence of a non-equilibrium attractor that is an invariant manifold determined by the long-wavelength modes of the physical system.

Submersions of generic submanifolds of a Kaehler manifold
Arab Journal of Mathematical Sciences, 2014 Kobayashi has shown that for the submersion π:M→B of a CR-submanifold of a Kaehler manifold M¯ onto an almost Hermitian manifold B,B is necessarily a Kaehler manifold.

Multiply Warped Product Generalized Semi-Invariant Submanifolds
International Electronic Journal of Geometry, 2021 We define generalized semi-invariant submanifolds in locally product Riemannian manifolds. Then we study multiply warped product generalized semi-invariant submanifolds in the same structure. We give an existence theorem for such submanifolds. We also give necessary and sufficient conditions for such a submanifold to be a multiply direct product ...

Chen optimal inequalities of CR-warped products of generalized Sasakian space form
Journal of Taibah University for Science, 2020 Our main objective of this paper is to derive the relationship between the main extrinsic invariant, and the contact CR δ-invariant (new intrinsic invariant) on a generic submanifold in trans-Sasakian generalized Sasakian space forms.
