This paper presents a study of contact metric manifolds for which the characteristic vector
field of the contact structure satisfies a nullity type condition, condition (*) below. There are a …

Inspired by a result of Boyer and Galicki, we prove that a complete K-contact gradient soliton
is compact Einstein and Sasakian. For the non-gradient case we show that the soliton vector …

In a 3-dimensional trans-Sasakian manifold, explicit formulae for Ricci operator, Ricci tensor
and curvature tensor are obtained. In particular, expressions for Ricci tensor are obtained in …

A contact manifold (M, o9) is said to be homogeneous [8] if there is a connected Lie group G
acting transitively as a group of diffeomorphisms on M which leave the contact form co …

Representative examples of uniform magnetic fields are furnished by Kähler magnetic fields.
From this point of view, magnetic Jacobi fields on surfaces or Kähler manifolds were …

We extend the notion of a locally T-symmetric space to the class of contact metric manifolds
using reflections with respect to characteristic curves. We show that the only locally T …

The notion of quasi-Einstein manifolds arose during the study of exact solutions of the
Einstein field equations as well as during considerations of quasi-umbilical hypersurfaces …
