The subject of the present paper is the investigation of a new type of solitons, called η-∗-
Ricci solitons in (k, μ)-almost co-Kähler manifold (briefly, ackm), which generalizes the …

A Riemann soliton (RS) is a natural generalization of a Ricci soliton structure on pseudo‐
Riemannian manifolds. This work aims at investigating almost co‐Kählerian manifolds …

In this paper, we obtain some classification results of three-dimensional non-coKähler
almost coKähler manifold M whose Reeb vector field is strongly normal unit vector field with …

The aim of the present paper is to characterize almost co-Kähler manifolds whose metrics
are the Riemann solitons. At first we provide a necessary and sufficient condition for the …

The aim of this paper is to characterize almost co-Kähler manifolds and co-Kähler three-
manifolds whose metrices are the gradient ρ-Einstein solitons. At first we prove that a proper …

In the present paper, we have studied Miao-Tam equation on three dimensional almost
coKähler manifolds. We have also proved that there does not exist non-trivial solution of …

Let M 3 be a strictly almost cosymplectic three-manifold whose Ricci operator is weakly ϕ-
invariant. In this article, it is proved that Ricci curvatures of M 3 are invariant along the Reeb …

Let M be an almost cosymplectic 3‐h‐a‐manifold. In this paper, we prove that the Ricci
operator of M is transversely Killing if and only if M is locally isometric to a product space of …
