Charakterisierungen spezieller windschiefer Regelflächen durch die Normalkrümmung ausgezeichneter Flächenkurven

Abstract

We consider ruled surfaces in the three-dimensional Euclidean space and some geometrically distinguished families of curves on them whose normal curvature has a concrete form. The aim of this paper is to find and classify all ruled surfaces with the mentioned property
