ON NORMAL ALMOST PARACONTACT METRIC MANIFOLDS OF DIMENSION 3 [PDF]

, 2015
In this study, we make the first contribution to investigate under which conditions normal almost paracontact metric manifold of dimension 3 has cyclic parallel Ricci tensor, η-parallel Ricci tensor, Ricci-semisymmetry and locally ϕ-symmetry. Finally, an

$η$-Ricci Solitons on Kenmotsu 3-Manifolds

In the present paper we study $η$-Ricci solitons on Kenmotsu 3-manifolds. Moreover, we consider $η$-Ricci solitons on Kenmotsu 3-manifolds with Codazzi type of Ricci tensor and cyclic parallel Ricci tensor.

On a class of Ricci-recurrent manifolds

, 2003
Properties of Ricci-recurrent manifolds with some conditions imposed on the Weyl conformal curvature tensor are investigated. The main theorem states: a conformally quasi-recurrent and Ricci-recurrent but not Ricci-parallel manifold of dimension n>4 with

ON THE RICCI TENSOR OF SUBMANIFOLDS IN CONFORMAL KENMOTSU MANIFOLDS

In this paper, we obtain several interesting results on submanifolds of conformal Kenmotsu manifolds. In addition to this we consider submanifolds of a conformal Kenmotsu manifolds of which the Ricci tensor is parallel, Lie ζ-parallel or recurrent.

The Ricci tensor of almost parahermitian manifolds

, 2018
We study the pseudoriemannian geometry of almost parahermitian manifolds, obtaining a formula for the Ricci tensor of the Levi–Civita connection. The formula uses the intrinsic torsion of an underlying SL(n,R)-structure; we express it in terms of ...

Ricci Solitons in β-Kenmotsu Manifolds

, 2018
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 tensor.

On Pseudo Cyclic Ricci Symmetric Manifolds

, 2011
: The object of the present paper is to study concircularly symmetric (PCRS)n, concircularly recurrent (PCRS)n, decomposable (PCRS)n. Among others it is shown that in a decomposable (PCRS)n one of the decompositions is Ricci flat and the other ...

On nonpositively curved compact Riemannian manifolds with degenerate Ricci tensor

, 2010
In this article, we prove that if the Ricci tensor of a compact nonpositively curved manifold M n M^n is nowhere negative definite, then it admits local flat factors. To be more precise, let U ⊆
