On the Differential Equation Governing Torqued Vector Fields on a Riemannian Manifold
In this article, we show that the presence of a torqued vector field on a Riemannian manifold can be used to obtain rigidity results for Riemannian manifolds of constant curvature. More precisely, we show that there is no torqued vector field on n-sphere

A link between torse-forming vector fields and rotational hypersurfaces
Torse-forming vector fields introduced by Yano [On torse forming direction in a Riemannian space, Proc. Imp. Acad. Tokyo 20 (1944) 340–346] are natural extension of concurrent and concircular vector fields.

From infinitesimal harmonic transformations to Ricci solitons [PDF]
summary:The concept of the Ricci soliton was introduced by R. S. Hamilton. The Ricci soliton is defined by a vector field and it is a natural generalization of the Einstein metric.

Equitorsion holomorphically projective mappings of generalized Kählerian space of the first kind [PDF]
summary:In this paper we define generalized Kählerian spaces of the first kind $(G\underset 1K_N)$ given by (2.1)--(2.3). For them we consider hollomorphically projective mappings with invariant complex structure.

Sasakian Hypersurfaces of the Generalized Concircular Recurrent Kahlerian Manifold
In this paper we consider a recurrent sasakian hyper surface of the generalized con circular recurrent Kahlerian manifold and determine some conditions on the vector fields used in the sasakian structure.
