Focal curves according to ribbon roof in dual space

Many studies have been done on the theory of rektifying curves in Euclidean space. Many scientists have proven the torsion and curvature of there ctifying curve according to the arc lenght parameter. In this thesis, first of all detailed information about the Dual space, which forms the basis of the study, is given. Using this created content later, rektifying curves in Dual Space were defined.The dual curvature and torsion of these curves were expressed according to the dual the arc lenght parameter.Finally, a new characterization of dual spherical curves based on the Darboux vector was made.
