Generalized Kenmotsu Manifolds
Vanli, Aysel Turgut; Sari, Ramazan (RGN PUBL, 2016)In 1972, K. Kenmotsu studied a class of almost contact Riemannian manifolds which later are called a Kenmotsu manifold. In this paper, we study Kenmotsu manifolds with (2n + s)-dimensional s-contact metric manifold that ... -
Generic ??-Riemannian submersions
Sari, Ramazan (Hacettepe Univ, Fac Sci, 2022)As a generalization of semi-invariant xi(perpendicular to)-Riemannian submersions, we introduce the generic xi(perpendicular to)- Riemannian submersions. We focus on the generic xi(perpendicular to)-Riemannian submersions ... -
ON CR-SUBMANIFOLDS OF A S-MANIFOLD ENDOWED WITH A SEMI-SYMMETRIC NON-METRIC CONNECTION
Akyol, Mehmet Akif; Sari, Ramazan (ANKARA UNIV, FAC SCI, 2016)In this paper, we study CR-submanifolds of an S-manifold endowed with a semi-symmetric non-metric connection. We give an example, investigating integrabilities of horizontal and vertical distributions of CR-sub manifolds ... -
On Semi-Slant xi(perpendicular to)-Riemannian Submersions
Akyol, Mehmet Akif; Sari, Ramazan (SPRINGER BASEL AG, 2017)The aim of the present paper is to define and study semi-slant xi(perpendicular to)-Riemannian submersions from Sasakian manifolds onto Riemannian manifolds as a generalization of anti-invariant xi(perpendicular to)-Riemannian ... -
On special submanifolds of the Page space
Kalafat, Mustafa; Sari, Ramazan (Elsevier, 2021)In this paper, we study some classes of submanifolds of codimension one and two in the Page space. These submanifolds are totally geodesic. We also compute their curvature and show that some of them are constant curvature ... -
Semi-invariant xi(perpendicular to)-Riemannian submersions from almost contact metric manifolds
Akyol, Mehmet Akif; Sari, Ramazan; Aksoy, Elif (WORLD SCIENTIFIC PUBL CO PTE LTD, 2017)As a generalization of anti-invariant xi(perpendicular to)-Riemannian submersions, we introduce semiinvariant xi(perpendicular to)-Riemannian submersions from Sasakian manifolds onto Riemannian manifolds. We give examples, ... -
The Smallest Dimension Submanifolds of Para beta-Kenmotsu Manifold
Turgut Vanli, Aysel; Sari, Ramazan (GAZI UNIV, 2016)In this paper, we have studied the smallest dimensional submanifold of para beta-Kenmotsu manifold. Necessary and sufficient conditions are given on 3-dimensional submanifolds of a 5-dimensional para beta-Kenmotsu manifold ... -
Some Curvature Properties of CR-Submanifolds of an S-Manifold with a Quarter-Symmetric Non-Metric Connection
Sari, Ramazan; Akyol, Mehmet Akif; Aksoy, Elif (CENTRE ENVIRONMENT SOCIAL & ECONOMIC RESEARCH PUBL-CESER, 2017)The purpose of this paper is to study CR-submanifolds of an S-manifold endowed with a quarter symmetric non-metric connection. We investigate that some properties of CR-submanifolds of an S-space form a quarter symmetric ...
