Geometry of Warped Product CR and Semi-Slant Submanifolds in Quasi-Para-Sasakian Manifolds

open access: yesInternational Journal of Analysis and Applications, 2022
In the present paper we study the existence or non-existence of warped product semi-slant submanifolds in quasi-para-Sasakian manifolds and prove that there are no proper warped product semi-slant submanifolds in a quasi-para-Sasakian manifold such that ...

Pseudoparallel Invariant Submanifolds of a Para-Sasakian Manifold

open access: yesTurkish Journal of Mathematics and Computer Science, 2023
In this paper, invariant submanifolds of a para-Sasakian manifold have been studied. Some special submanifolds such as pseudoparallel, 2-pseudoparallel, Ricci generalized pseudoparallel, and 2-Ricci generalized pseudoparallel submanifolds of a para-Sasakian manifold have been considered.

On Quasi Hemi-Slant Submersions

open access: yesCommunications in Advanced Mathematical Sciences, 2023
The paper deals with the notion of quasi hemi-slant submersions from Lorentzian para Sasakian manifolds onto Riemannian manifolds. These submersions are generalization of hemi-slant submersions and semi-slant submersions. In this paper, we also study the

Homology of Warped Product Semi‐Invariant Submanifolds of a Sasakian Space Form with Semisymmetric Metric Connection

open access: yesJournal of Mathematics, Volume 2023, Issue 1, 2023., 2023
This paper focuses on the investigation of semi‐invariant warped product submanifolds of Sasakian space forms endowed with a semisymmetric metric connection. We delve into the study of these submanifolds and derive several fundamental results. Additionally, we explore the practical implications of our findings by applying them to the homology analysis ...

Anti-quasi-Sasakian manifolds [PDF]

open access: yes, 2023
We introduce and study a special class of almost contact metric manifolds, which we call anti-quasi-Sasakian (aqS). Among the class of transversely Kahler almost contact metric manifolds (M, phi, xi, eta, g), quasi-Sasakian and anti-quasi-Sasakian ...

G2${\mathrm{G}}_2$‐instantons on the 7‐sphere

open access: yesJournal of the London Mathematical Society, Volume 106, Issue 4, Page 3711-3745, December 2022., 2022
Abstract We study the deformation theory of G2${\mathrm{G}}_2$‐instantons on the round 7‐sphere, specifically those obtained from instantons on the 4‐sphere via the quaternionic Hopf fibration. We find that the pullback of the standard ASD instanton lies in a smooth, complete, 15‐dimensional family of G2${\mathrm{G}}_2$‐instantons.

Indefinite Almost Paracontact Metric Manifolds

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2010
We introduce the concept of (ε)-almost paracontact manifolds, and in particular, of (ε)-para-Sasakian manifolds. Several examples are presented. Some typical identities for curvature tensor and Ricci tensor of (ε)-para Sasakian manifolds are obtained. We
