    • Characterizing killing vector fields of standard static space-times 

      Dobarro, F.; Ünal, B. (Elsevier, 2012)
      We provide a global characterization of the Killing vector fields of a standard static space-time by a system of partial differential equations. By studying this system, we determine all the Killing vector fields in the ...
    • Curvature in special base conformal warped products 

      Dobarro F.; Ünal, B. (Springer Netherlands, 2008)
      We introduce the concept of a base conformal warped product of two pseudo-Riemannian manifolds. We also define a subclass of this structure called as a special base conformal warped product. After, we explicitly mention ...
    • Implications of energy conditions on standard static space-times 

      Dobarro, F.; Ünal, B. (Pergamon Press, 2009)
      In the framework of standard static space-times, we state a family of sufficient or necessary conditions for a set of physically reasonable energy and convergence conditions in relativity and related theories. We concentrate ...
