Focal curves according to ribbon roof in dual space

Many studies have been carried out according to different frameworks in the theory of curves in Euclidean space. Many scientists have studied roofs such as Frenet roof, Bishop roof, Adapted roof, Ribbon roof in this theory. These frameworks help us with characterizations about curves. In this thesis, first of all detailed information about dual the Dual space, which forms the basis of the study, is given. Using this created content later, Focal Curves in Dual Space were defined. Finally, by expressing the Ribbon roof in Dual Space, the dual Focal Curves was expresswd according to this framework.
