    • 2-Killing vector fields on warped product manifolds 

      Shenawy, S.; Ünal, B. (World Scientific Publishing, 2015)
      This paper provides a study of 2-Killing vector fields on warped product manifolds as well as characterization of this structure on standard static and generalized Robertson-Walker space-times. Some conditions for a 2-Killing ...
    • Sequential warped products: curvature and conformal vector fields 

      Chand De, Uday; Shenawy, S.; Ünal, Bülent (University of Nis, 2019)
      In this note, we introduce a new type of warped products called as sequential warped products to cover a wider variety of exact solutions to Einstein’s field equation. First, we study the geometry of sequential warped ...
