Geometry of warped product semi-slant submanifolds of Kenmotsu manifolds
, 2017 In this paper, we study semi-slant submanifolds and their warped products in Kenmotsu manifolds. The existence of such warped products in Kenmotsu manifolds is shown by an example and a characterization.

Harmonic (p, q)‐Curves in Trans‐Sasakian and Normal Almost Paracontact Metric Manifolds
Journal of Mathematics, Volume 2025, Issue 1, 2025.In this paper, we give some characterizations about biharmonic, f‐harmonic, and f‐biharmonic (p, q)‐curves in 3‐dimensional trans‐Sasakian and normal almost paracontact metric manifolds. The (p, q)‐curves are considered as generalizations of magnetic curves.

Thoracic Cancer, Volume 15, Issue 21, Page 1665-1672, July 2024.We retrospectively evaluated the performance of frozen cell pellets from cytology specimens (FCPs) in the Amoy 9‐in‐1 assay. The success rates of DNA and RNA analyses were both 100% in Amoy 9‐in‐1 assay, compared with 86% and 45%, using NGS assay. Although the coverage of Amoy 9‐in‐1 is limited compared to NGS assays, the Amoy using FCPs can be a ...

The Z‐Tensor on Almost Co‐Kählerian Manifolds Admitting Riemann Soliton Structure
Advances in Mathematical Physics, Volume 2024, Issue 1, 2024.A Riemann soliton (RS) is a natural generalization of a Ricci soliton structure on pseudo‐Riemannian manifolds. This work aims at investigating almost co‐Kählerian manifolds (ACKM) 2n+1 whose metrics are Riemann solitons utilizing the properties of the Z‐tensor.

A Note on Doubly Warped Product Contact CR-Submanifolds in trans-Sasakian Manifolds
, 2007 Warped product CR-submanifolds in Kaehlerian manifolds were intensively studied only since 2001 after the impulse given by B.Y. Chen. Immediately after, another line of research, similar to that concerning Sasakian geometry as the odd dimensional version

, 2022 In the present paper, we introduce a new class of structures on an even dimensional differentiable Riemannian manifold which combines, well known in literature, the Sasakian and Kenmotsu structures simultaneously. The structure will be called a Sasaki-Kenmotsu structure by us.

Nearly Kahler and nearly Kenmotsu manifolds
TURKISH JOURNAL OF MATHEMATICS, 2018 Summary: We study the class of strict nearly Kenmotsu manifolds and prove that there is no Einstein manifold or locally symmetric or locally \(\phi\)-symmetric in this class of manifolds. We describe strict nearly Kenmotsu manifolds in low dimensions.

Ricci Solitons in β -Kenmotsu Manifolds [PDF]
Annals of West University of Timisoara - Mathematics and Computer Science, 2018 Abstract The object of the present paper is to study Ricci soliton in β -Kenmotsu manifolds. Here it is proved that a symmetric parallel second order covariant tensor in a β -Kenmotsu manifold is a constant multiple of the metric ...
