Nullity conditions in paracontact geometry
B. Cappelletti Montano, I. Kupeli Erken, C. Murathan
The paper is a complete study of paracontact metric manifolds for which the Reeb vector field of the underlying contact structure satisfies a nullity condition (the condition \eqre…

A class of 3-dimensional contact metric manifolds
Irem Küpeli Erken, Cengizhan Murathan
We classify the contact metric 3-manifolds that satisfy ||gradλ||=1 and \nabla_{ξ}τ=2aτϕ.

Biharmonic Pseudo-Riemannian submersions from 3-manifolds
Irem Küpeli Erken, Cengizhan Murathan
We classify the pseudo-Riemannian biharmonic submersion from a 3-dimensional space form into a surface.
