Homology of contact CR-submanifolds
Fulya Sahin, Bayram Sahin
In this paper, homology of a contact CR-submanifold of a real hypersurface, which has naturally almost contact metric structure induced from the complex Euclidean space $\mathbb{C}…
Sequential warped product submanifolds having factors as holomorphic, totally real and pointwise slant
Bayram Sahin
We introduce sequential warped product submanifolds of Kaehler manifolds, provide examples and establish Chen's inequality for such submanifolds. The equality case is also studied.…
Conformal anti-invariant submersions from almost Hermitian manifolds
Mehmet Akif Akyol, Bayram Sahin
We introduce conformal anti-invariant submersions from almost Hermitian manifolds onto Riemannian manifolds. We give examples, investigate the geometry of foliations which are aris…

It is known that there exist no warped product semi-slant submanifolds in Kaehler manifolds \cite{Sahin}. Recently, Chen and Garay studied pointwise-slant submanifolds of almost He…

Feyza Esra Erdogan, Rifat Gunes, Bayram Sahin
We investigate half-lightlike submanifolds with planar normal sections of four dimensional pseudo Euclidean space. We obtain necessary and sufficient conditions for a half-lightlik…

Feyza Esra Erdogan, Bayram Sahin, Rifat Gunes
In this paper we study lightlike surfaces of Minkowski 3- space such that they have degenerate or non-degenerate planar normal sections. We first show that every lightlike surface…
