ON FRAMED METRIC SUBMANIFOLDS [PDF]

application/pdfIn the present paper, we have obtained the necessary and sufficient conditions for framed metric submanifolds of almost Hermite manifold to posses a certain structure. Also the conditions for framed metric submanifolds of Kahler and almost

On the normality of an almost contact $3$-structure on $QR$-submanifolds [PDF]

, 1971
summary:We study $n$-dimensional $QR$-submanifolds of $QR$-dimension $(p-1)$ immersed in a quaternionic space form $QP^{(n+p)/4}(c)$, $c\geqq 0$, and, in particular, determine such submanifolds with the induced normal almost contact $3 ...

Rigidity of Minimal Legendrian Submanifolds in Sasakian Space Forms

Journal of Mathematics
This paper is concerned with the study on rigidity of minimal Legendrian submanifolds in Sasakian space forms under some certain geometric conditions, motivated by the classification of minimal Legendrian submanifolds with constant sectional curvature ...

Coordinate Finite-Type Submanifolds [PDF]

, 1991
A submanifold of a Euclidean space is called a coordinate finite-type submanifold if its coordinate functions are eigenfunctions of DELTA. We prove that the compact coordinate finite-type submanifolds are minimal submanifolds of quadratic hypersurfaces ...

Some Results on Warped Product Submanifolds of a Sasakian Manifold

International Journal of Mathematics and Mathematical Sciences, 2010
We study warped product Pseudo-slant submanifolds of Sasakian manifolds. We prove a theorem for the existence of warped product submanifolds of a Sasakian manifold in terms of the canonical structure 𝐹.

CR STATISTICAL SUBMANIFOLDS

Kyushu Journal of Mathematics, 2019
Summary: The non-existence of CR submanifolds of maximal CR dimension with umbilical shape operator in holomorphic statistical manifolds is proven. Our results are a generalization of the known results in the theory of CR submanifolds in complex space forms.
