Half-lightlike submanifolds with planar normal section in
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…

Lightlike surfaces with planar normal sections in Minkowski 3-space
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…
