Certain results on invariant submanifolds of para-Kenmotsu manifolds

, 2021
Summary: The purpose of this paper is to study invariant pseudoparallel, Ricci generalized pseudoparallel and 2-Ricci generalized pseudoparallel submanifold of a para-Kenmotsu manifold and I obtained some equivalent conditions of invariant submanifolds of para-Kenmotsu manifolds under some conditions which the submanifolds are totally geodesic. Finally,

STUDY ON DIFFERENT TYPES OF CONNECTIONS ON CHAKI-PSEUDO PARALLEL INVARIANT SUBMANIFOLDS OF LORENTZIAN PARA-KENMOTSU MANIFOLD

South East Asian J. of Mathematics and Mathematical Sciences
The focus of this research is to investigate Chaki-pseudo parallel submanifolds in Lorentzian para-Kenmotsu manifolds. This study examines the properties of these submanifolds, including their totally geodesic nature under different connections such as ...

Slant curves in 3-dimensional normal almost paracontact metric manifolds

, 2012
The presented paper is devoted to study the curvature and torsion of slant Frenet curves in 3-dimensional normal almost paracontact metric manifolds. Moreover, in this class of manifolds, properties of non- Frenet slant curves (with null tangents or null

Generalized Z‐Solitons on LP‐Sasakian Manifolds With the General Connection

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This work focuses on LP‐Sasakian manifolds endowed with generalized Z‐solitons constructed with respect to an arbitrary affine connection. To conclude, we provide an explicit and nontrivial example in the four‐dimensional case, thereby establishing the realization of such solitons on LP‐Sasakian manifolds.

LP-Kenmotsu Manifolds Admitting Bach Almost Solitons

Universal Journal of Mathematics and Applications
For a Lorentzian para-Kenmotsu manifold of dimension $m$ (briefly, ${(LPK)_{m}}$) admitting Bach almost soliton $(g,\zeta,\lambda)$, we explored the characteristics of the norm of Ricci operator. Besides, we gave the necessary condition for ${(LPK)_{m}}

Optimization of Soliton Structures Using Lifting Theory on Tangent Bundles of Statistical Kenmotsu Manifolds

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This paper investigates the optimization of soliton structures on tangent bundles of statistical Kenmotsu manifolds through lifting theory. By constructing lifted statistical Kenmotsu structures using semisymmetric metric and nonmetric connections, we derive explicit expressions for the curvature tensor, Ricci operator, and scalar curvature. We analyze

Desensitizing Effect of Intra‐Tumoral GDF‐15 on Immunotherapy in Patients With Advanced Non‐Small Cell Lung Cancer

Thoracic Cancer, Volume 16, Issue 10, May 2025.
Intra‐tumoral GDF‐15 expression was assessed in advanced NSCLC patients receiving PD‐1/PD‐L1 monotherapy. GDF‐15 high levels were strongly associated with cancer cachexia and significantly poorer clinical outcomes, suggesting its potential as a predictive biomarker for immunotherapy efficacy.

α-almost Ricci solitons on Kenmotsu manifolds [PDF]

, 2020
The current article purports to investigate α-almost Ricci solitons in the framework of Kenmotsu manifolds. Among others, we prove that an α- almost Ricci solitons on a Kenmotsu manifold is expanding.
