In the context of paracontact geometry, $\eta $-Ricci solitons are considered on manifolds
satisfying certain curvature conditions: $(\xi,\cdot) _ {R}\cdot S= 0$, $(\xi,\cdot) _ {S}\cdot R …

We set a type of semi-symmetric metric connection on the Lorentzian manifolds. It is proved
that a Lorentzian manifold endowed with a semi-symmetric metric ρ ρ-connection is a GRW …

Geometrical aspects of a perfect fluid spacetime are described in terms of different curvature
tensors and η-Ricci and η-Einstein solitons in a perfect fluid spacetime are determined …

Torse-forming 𝜂-Ricci solitons are studied in the framework of almost paracontact metric 𝜂-
Einstein manifolds. By adding a technical condition, called regularity and concerning with …

We define a class of semi-symmetric metric connection on a Riemannian manifold for which

In the paper, we study a Ricci soliton and a generalized m-quasi-Einstein metric on almost
co-Kaehler manifold M satisfying a nullity condition. First, we consider a non-co-Kaehler (κ …

In this paper, we prove that if there exists a second order symmetric parallel tensor on an
almost Kenmotsu manifold (𝑀2𝑛+ 1, 𝜙, 𝜉, 𝜂, 𝑔) whose characteristic vector field 𝜉 belongs …

In this paper, we deal with the geometric properties of cosymplectic manifold. We give some
classifications for a cosymplectic manifold endowed with some special vector fields, such as …
