Doubly warped products
B Ünal - Differential Geometry and Its Applications, 2001 - Elsevier
In this paper we study geodesic completeness of Riemannian doubly warped products and
Lorentzian doubly warped products. We give necessary conditions for generalized Robertson…

Multiply warped products
B Ünal - Journal of Geometry and Physics, 2000 - Elsevier
In this paper, we first state covariant derivative formulas for multiply warped products and
consider the geodesic equations for these spaces. Then we state some basic facts about …

Curvature of multiply warped products
F Dobarro, B Ünal - Journal of Geometry and Physics, 2005 - Elsevier
In this paper, we study Ricci-flat and Einstein–Lorentzian multiply warped products. We also
consider the case of having constant scalar curvatures for this class of warped products. …

Geodesic structure of standard static space–times
DE Allison, B Ünal - Journal of Geometry and Physics, 2003 - Elsevier
The geodesic structure of standard static space–times is studied and conditions are found
which imply nonreturning and pseudoconvex geodesic systems. As a consequence, it is …
