The Geometry of Invariant Submanifolds of a (κ,μ)-Paracontact Metric Manifold

open access: yesInternational Journal of Pioneering Technology and Engineering, 2022
In this article, we consider an invariant submanifold of a -paracontact metric manifold. We research the conditions   and  for an invariant submanifold of a paracontact metric manifold.

Real submanifolds of maximum complex tangent space at a CR singular point [PDF]

open access: yes, 2014
We study a germ of real analytic $n$-dimensional submanifold of ${\mathbf C}^n$ that has a complex tangent space of maximal dimension at a CR singularity. Under the condition that its complexification admits the maximum number of deck transformations, we

Pseudo-Isotropic Centro-Affine Lorentzian Surfaces

open access: yesMathematics, 2020
In this paper, we study centro-affine Lorentzian surfaces M2 in ℝ3 which have pseudo-isotropic or lightlike pseudo-isotropic difference tensor. We first show that M2 is pseudo-isotropic if and only if the Tchebychev form T=0.

Warped product semi-slant submanifolds in locally conformal Kaehler manifolds II

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2018
In 1994 N.~Papaghiuc introduced the notion of semi-slant submanifold in a Hermitian manifold which is a generalization of $CR$- and slant-submanifolds, \cite{MR0353212}, \cite{MR760392}.

Calibrated Submanifolds [PDF]

open access: yes, 2020
We provide an introduction to the theory of calibrated submanifolds through the key examples related with special holonomy. We focus on calibrated geometry in Calabi-Yau, G$_2$ and Spin(7) manifolds, and describe fundamental results and techniques in the field.

On Geometry of Submanifolds of (LCS)𝑛-Manifolds

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2012
We show geometrical properties of a submanifold of a (LCS)𝑛-manifold. The properties of the induced structures on such a submanifold are also studied.

A note on quasi-hemi slant submanifolds of nearly trans-Sasakian manifolds [PDF]

open access: yesJournal of Hyperstructures, 2023
Here our main objective is to introduce the notion of quasi hemi-slant submanifolds as a generalized case of slant sub-manifolds, semi-slant submanifolds and hemi-slant submanifolds of contact metric manifolds.

On Chasles' Property of the Helicoid in Tri-Twisted Real Ambient Space

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
An elementary property of the helicoid is that at every point of the surface the following condition holds: cot θ = C · d; where d is the distance between an arbitrary point to the helicoid axis, and θ is the angle between the normal and the helicoid’s ...
