Critical metrics with cyclic parallel Ricci tensor for volume functional on manifolds with boundary

Geometriae Dedicata, 2018
In this paper, the authors study the critical metrics with cyclic parallel Ricci tensor for volume functional on compact manifolds \((M^n,g)\), \((n\ge 3)\), with boundary \(\partial M\). A Riemannian metric \(g\) is said to be with cyclic parallel Ricci tensor if its Ricci tensor satisfies \(\nabla_X \mathrm{Ric}(Y,Z)+\nabla_Y \mathrm{Ric}(Z,X ...

Real Hypersurfaces in ℂP 2 and ℂH 2 with Cyclic Parallel ∗-Ricci Tensor

Studia Scientiarum Mathematicarum Hungarica, 2021
In this paper, we prove that the ∗-Ricci tensor of a real hypersurface in complex projective plane ℂP 2 or complex hyperbolic plane ℂH 2 is cyclic parallel if and only if the hypersurface is of type (A). We find some three-dimensional real hypersurfaces having non-vanishing and non-parallel ∗-Ricci tensors which are cyclic

Cyclic-parallel Ricci tensors on a class of almost Kenmotsu 3-manifolds

International Journal of Geometric Methods in Modern Physics, 2019
In this paper, we give a local characterization for the Ricci tensor of an almost Kenmotsu [Formula: see text]-manifold [Formula: see text] to be cyclic-parallel. As an application, we prove that if [Formula: see text] has cyclic-parallel Ricci tensor and satisfies [Formula: see text], (where [Formula: see text] is the Lie derivative of [Formula: see ...
