On a class of Ricci-recurrent manifolds
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

SUBMANIFOLDS OF A RIEMANNIAN MANIFOLD ADMITTING A TYPE OF RICCI QUARTER-SYMMETRIC METRIC CONNECTION [PDF]
The object of the present paper is to study submanifolds of aRiemannian manifold admitting a type of Ricci quater-symmetric metric connection.We have proved that the induced connection is also a Ricci quartersymmetricmetric connection.

On 3-dimensional generalized (kappa, mu)-contact metric manifolds
In the present study, we considered 3-dimensional generalized (kappa, mu)-contact metric manifolds. We proved that a 3-dimensional generalized (kappa, mu)-contact metric manifold is not locally phi-symmetric in the sense of Takahashi.
