Lightlike(null) koni üzerinde eğriler ve karakterizasyonları
Özet
This thesis consists of five chapters. The first chapter is devoted to the introduction. The second chapter, basic definitions and concepts are given. In the third chapter, curve-surface curvatures are investigated for a lightlike surface in 3-dimensional Minkowski space. In the fourth chapter, curves in the lightlike cone are investigated and various characterizations related to these curves are given. The last chapter, helices in the 2-dimensional lightlike cone and 3-dimensional lightlike cone are investigated.
