On Inextensible Flows Developable Surfaces Associated Focal Curve According to Ribbon Frame

Özet

In this paper, we investigate inextensible flows of focal curves in Euclidean 3-space E3 associated to developable surfaces to ribbon frame. We present some new generalizations for torsion and curvature of focal curves in E3 associated to developable surfaces. Finally, in case of having a flow of developable surface is inextensible we prove that this surface is not minimal.
