A characterization of totally umbilical hypersurfaces of a space form by geodesic mapping
Canfes, Elif Ozkara; Özdeğer, Abdülkadir (Springer, 2013)The idea of considering the second fundamental form of a hypersurface as the first fundamental form of another hypersurface has found very useful applications in Riemannian and semi-Riemannian geometry especially when ... -
Chebyshev nets formed by Ricci curves in a 3-dimensional Weyl space
Yıldırım, Gülçin Çivi; Özdeğer, Abdülkadir (Elsevier Science Bv, 2005)In this paper Ricci curves in a 3-dimensional Weyl space W-3(g T) are defined and it is shown that any 3-dimensional Chebyshev net formed by the three families of Ricci curves in a W-3(g T) having a definite metric and ... -
Conformal and generalized concircular mappings of Einstein-Weyl manifolds
Özdeğer, Abdülkadir (2010)In this article after giving a necessary and sufficient condition for two Einstein-Weyl manifolds to be in conformal correspondence we prove that any conformal mapping between such manifolds is generalized concircular if ... -
Generalized Einstein tensor for a Weyl manifold and its applications
Özdeğer, Abdülkadir (Springer Heidelberg, 2013)It is well known that the Einstein tensor G for a Riemannian manifold defined by R (alpha) (beta) = g (beta gamma) R (gamma I +/-) where R (gamma I +/-) and R are respectively the Ricci tensor and the scalar curvature of ... -
On sectional curvatures of a Weyl manifold
Özdeğer, Abdülkadir (2006)In this paper it is proved that if at each point of a Weyl manifold the sectional curvature is independent of the plane chosen then the Weyl manifold is locally conformal to an Einstein manifold and that the scalar curvature ...
