On a Lorentzian para-Sasakian manifold withrespect to the quarter-symmetric metricconnection

, 2016
In this paper, we study certain curvature conditions satisfied by the conharmonic curvature tensor in a Lorentzian para-Sasakian manifold with respect to the quarter-symmetric metric connection.

On Real Cohomology Generators of Compact Homogeneous Spaces

Sarajevo Journal of Mathematics
In this paper we discuss the degrees of real cohomology generators of compact homogeneous spaces. We relate these degrees to rational homotopy groups and, furthermore, we discuss the formality and geometric formality of compact homogeneous spaces in the ...

B.-Y. Chen Inequalities for Slant Submanifolds in Kenmotsu Space Forms II

Sarajevo Journal of Mathematics
In this article, we investigate sharp inequalities involving Chen invariants for a slant submanifold $M$ of a Kenmotsu space form $\widetilde{M}(c)$, tangent to the structure vector field of the ambient space.   2000 Mathematics Subject Classification.

-Ricci Solitons On Sasakian Manifolds Admitting General Connection

Journal of Mountain Research
In this paper we study -Ricci soliton on Sasakian manifolds admitting general connection and obtain some conditions for the soliton to be shrinking, steady and expanding. MSC 2020: 53C15, 53C25, 53D15.

On Special Weakly Ricci-Symmetric Kenmotsu Manifolds

Sarajevo Journal of Mathematics
In this paper, we have studied special weakly Ricci symmetric Kenmotsu manifolds. We show that if a special weakly Riccisymmetric Kenmotsu manifold admits a cyclic parallel Ricci tensor then the associate 1–form $\alpha$ must be zero.
