On contact metric hypersurfaces in a real space form
Özgür, Cihan; Tripathi, Mukut Mani; Hong, Sungpyo (Academic Publication Council, 2007)For a (2n + 1)-dimensional N(k)-contact metric hypersurface in a real space form (M) over tilde (c), some main results are obtained as follows: (1) if k - c > 0 then M is totally umbilical, and consequently, either M is a ... -
On legendre curves in alpha-sasakian manifolds
Özgür, Cihan; Tripathi, Mukut Mani (Malaysian Mathematical Sciences Soc, 2008)The torsion of a Legendre curve of an alpha-Sasakian manifold is obtained. Necessary and sufficient conditions for Legendre curves having parallel mean curvature vector, having proper mean curvature vector, being harmonic ... -
On P-Sasakian manifolds satisfying certain conditions on the concircular curvature tensor
Özgür, Cihan; Tripathi, Mukut Mani (Scientific Technical Research Council Turkey-Tubitak, 2007)We classify P-Sasakian manifolds, which satisfy the conditions Z(xi,X). Z = 0, Z(xi, X) . R = 0, R(xi, X) . Z = 0, Z(xi, X) . S = 0 and Z(xi, X) . C = 0. -
On some special classes of Kenmotsu manifolds
Hong, Sungpyo; Özgür, Cihan; Tripathi, Mukut Mani (Academic Publication Council, 2006)We investigate the classes of Kenmotsu manifolds which satisfy the condition of being eta-Einstein, having eta-parallel Ricci tensor, R(xi, X) (.) Z = 0, R(xi, X) (.) R = 0, Z(xi, X) (.) Z = 0, Z(xi, X) (.) R = 0, Z(xi, ... -
On submanifolds satisfying chen's equality in a real space form
Özgür, Cihan; Tripathi, Mukut Mani (Springer Heidelberg, 2008)Einstein, conformally flat, semisymmetric, and Ricci-semisymmetric submanifolds satisfying Chen's equality in a real space form are studied. We prove that an n-dimensional (n >= 3) submanifold of a real space form (M) over ... -
On the contact conformal curvature tensor of a contact metric manifold
Kim, Jeong-Sik; Choi, Jaedong; Özgür, Cihan; Tripathi, Mukut Mani (Indian Nat Sci Acad, 2006)The contact conformal curvature tensor of an N(kappa)-contact rhetric manifolds is studied. We prove that an N(kappa)-contact metric manifold with vanishing extended contact conformal curvature tensor is a Sasakian manifold. ...
