CR-Submanifolds of Semi-Riemannian Kaehler Manifolds [PDF]
, 2016 First, we review the preliminaries and basic formulas for the CR-submanifold of a Kaehler manifold. Allowing the Kaehler metric to be of all signatures compatible with the Hermitian structure, we recall the results on mixed foliate, normal mixed totally ...

On Submersion of CR-Submanifolds of l.c.q.K. Manifold [PDF]
ISRN Geometry, 2012 We study submersion of CR-submanifolds of an l.c.q.K. manifold. We have shown that if an almost Hermitian manifoldBadmits a Riemannian submersionπ:M→Bof a CR-submanifoldMof a locally conformal quaternion Kaehler manifoldM¯, thenBis a locally conformal quaternion Kaehler manifold.

Bi-Slant Submanifolds of Para Hermitian Manifolds
Mathematics, 2019 In this paper, we introduce the notion of bi-slant submanifolds of a para Hermitian manifold. They naturally englobe CR, semi-slant, and hemi-slant submanifolds. We study their first properties and present a whole gallery of examples.

Warped product semi-slant submanifolds in locally conformal Kaehler manifolds
Pracì Mìžnarodnogo Geometričnogo Centru, 2017 In 1994, in [13], N. Papaghiuc introduced the notion of semi-slant submanifold in a Hermitian manifold which is a generalization of CR- and slant-submanifolds. In particular, he considered this submanifold in Kaehlerian manifolds, [13]. Then, in 2007, V.

Umbilical CR submanifolds of the nearly Kahler S^3xS^3 [PDF]
, 2022 Recently, the investigation of a CR submanifolds of the nearly Kähler manifold S^3×S^3 was started. After obtained classifications with respect to positions which the distributions D_1, D_2 and D_3 have under an action of the almost product structure P,

A Note on LP-Sasakian Manifolds with Almost Quasi-Yamabe Solitons
Journal of Mathematics, 2021 We categorize almost quasi-Yamabe solitons on LP-Sasakian manifolds and their CR-submanifolds whose potential vector field is torse-forming, admitting a generalized symmetric metric connection of type α,β.

Normal holonomy of CR submanifolds
, 2013 We study the normal holonomy group, i.e. the holonomy group of the normal connection, of a CR-submanifold of a complex space form. We show that the normal holonomy group of a coisotropic submanifold acts as the holonomy representation of a Riemannian symmetric space.

Flexible and inflexible $CR$ submanifolds [PDF]
Arkiv för Matematik, 2019 In this paper we prove new embedding results for compactly supported deformations of $CR$ submanifolds of $\mathbb{C}^{n+d}$: We show that if $M$ is a $2$-pseudoconcave $CR$ submanifold of type $(n,d)$ in $\mathbb{C}^{n+d}$, then any compactly supported $CR$ deformation stays in the space of globally $CR$ embeddable in $\mathbb{C}^{n+d}$ manifolds ...
