Chen inequalities for submanifolds of a cosymplectic space form with a semi-symmetric metric connection
Özgür, Cihan; Murathan, Cengizhan (Univ Al İ Cuza, 2012)In this paper, we prove Chen inequalities for submanifolds of a cosymplectic space form of constant phi-sectional curvature N2m+1(c) endowed with a semi-symmetric metric connection, i.e., relations between the mean curvature ... -

Özgür, Cihan; Murathan, Cengizhan (Ovidius Univ Press, 2010)In this paper we prove Chen inequalities for submanifolds of a locally conformal almost cosymplectic manifold N(2m+1)(c) of constant phi-sectional curvature c endowed with a semi-symmetric metric connection, i.e., relations ... -
On a class of surfaces in the Euclidean space
Özgür, Cihan; Arslan, Kadri; Murathan, Cengizhan (2002)In this study we consider surfaces in the Euclidean space E2+d satisfying the conditions Undefined control sequence \centerdot h = LhQ(g,h) and Undefined control sequence \centerdot h = LAHQ^(AH,h). -
On invariant submanifolds of lorentzian para-sasakian manifolds
Özgür, Cihan; Murathan, Cengizhan (King Fahd Univ Petroleum Minerals, 2009)We consider semiparallel and 2-semiparallel invariant submanifolds of Lorentzian para-Sasakian manifolds. We show that these submanifolds are totally geodesic. We also consider invariant submanifolds of Lorentzian para-Sasakian ... -

Özgür, Cihan; Murathan, Cengizhan; Arslan, Kadri (Kyungpook National University, 2009)We study on semiparallel and Weyl semiparallel Sasakian hypersurfaces of Kaehler manifolds. We prove that a (2n + 1)-dimensional Sasakian hypersurface M of a (2n+2)-dimensional Kaehler manifold M2n+2 is semiparallel if and ... -
On semiparallel anti-invariant submanifolds of generalized Sasakian space forms
Özgür, Cihan; Gürler, Fatma; Murathan, Cengizhan (Scientific Technical Research Council Turkey-Tubitak, 2014)We consider minimal anti-invariant semiparallel submanifolds of generalized Sasakian space forms. We show that the submanifolds are totally geodesic under certain conditions. -

Aminov, Yu.; Arslan, Kadri; Bayram, Bengü Kılıç; Bulca, Betül; Murathan, Cengizhan; Öztürk, Günay (B Verkin Inst Low Temperature Physics & Engineering, 2011)For the Monge-Ampere equation Z(xx)Z(yy) - Z(xy)(2) = b(20)(x2)+b(11).xy+b(02y)(2)+ b(00) we consider the question on the existence of a solution Z(x, y) in the class of polynomials such that Z = Z(x, y) is a graph of a ... -
Pinching theorems for totally real minimal submanifolds in cpn
Murathan, Cengizhan; Özgür, Cihan (Cambridge Univ Press, 2009)Let M be an n-dimensional totally real minimal submanifold in CPn. We prove that if M is semi-parallel and the scalar curvature tau, -(n-1)(n-2)(n+1)/2 <= tau <= 0, then M is an open part of the Clifford torus T-n subset ... -
Pseudo symmetric and pseudo Ricci symmetric warped product manifolds
We study pseudo symmetric (briefly (PS)n) and pseudo Ricci symmetric (briefly (PRS)n) warped product manifolds M ×F N. If M is (PS)n, then we give a condition on the warping function that M is a pseudosymmetric space and ... -

Recurrent immersions
Arslan, Kadri; Deszcz, Ryszard; Murathan, Cengizhan; Özgür, Cihan (Walter de Gruyter GmbH, 1999)In this paper we consider the relations between immersions of recurrent type with the immersions having certain planar properties. Namely, we investigate the weak recurrent immersions -

Arslan, Kadri; Bayram, Bengü Kılıç; Bulca, Betül; Kim, Young Ho; Murathan, Cengizhan; Öztürk, Günay (Scientific Technical Research Councıl Turkey-Tubitak, 2011)In the present article we study the rotational embedded surfaces in E-4. The rotational embedded surface was first studied by G. Ganchev and V. Milousheva as a surface in E-4. The Otsuki (non-round) sphere in E-4 is one ... -
