    New moving frames for the curves lying on a surface

    Alkan, Akın; Hüseyin, Kocayi̇Ği̇T; Ağirman Aydin, Tuba

    In this article, three new orthogonal frames are defined for the curves lying on a surface. These moving frames, obtained based on the Darboux frame, are called “Osculator Darboux Frame”, “Normal Darboux Frame” and “Rectifying Darboux Frame”, respectively. Also, the Osculator Darboux Frame components and curvatures are calculated for a presented example. Cite this article as: Alkan A, Kocayiğit H, Ağırman Aydın T.

    Di-Darboux Slant Helices on Surface

    Alkan, Akın; Kocayiğit, Hüseyin; Ağırman Aydın, Tuba

    In this study, we consider Di-Darboux slant helices which are new surface curves on an oriented surface. We give some characterizations for such curves according to the Darboux frame, OD-frame, ND-frame, RD-frame, and obtain axes of the Di-Darboux slant helices. Moreover, the position vectors of the Di-Darboux slant helices are obtained.
