Striction Lines of Non-developable Ruled Surfaces in Euclidean 3-Space

Öz

The ruled surfaces, one of the areas of interest of differential geometry, have been one of the surface

types studied by many mathematicians from the past to the present day. Similarly, some special curves which helix,

slant helix, Bertrand curve, etc. are also the curve types discussed often by mathematicians. In this paper, it will be

shown that striction lines of non-developable ruled surfaces are helix, slant helix, Bertrand or Mannheim curve in

some special cases.

Öklid-3 Uzayında Açılabilir Olmayan Regle Yüzeylerin Striksiyon Çizgileri

Öz

Diferansiyel geometrinin ilgi alanlarından olan regle yüzeyler, geçmişten günümüze bir çok matematikçi

tarafından çalışılan yüzey tiplerinden birisidir. Benzer şekilde helis, slant helis, Bertrand eğrisi gibi bazı özel

eğriler de matematikçiler tarafından sıklıkla tartışılan eğri tipleridir. Bu makalede, bazı özel durumlarda açılabilir

olmayan regle yüzeylerin striksiyon çizgilerinin helis, slant helis, Bertrand eğrisi ya da Mannheim eğrisi olduğu

gösterilecektir.
