A study of the inextensible ows of tube-like surfaces associated with focal curves in Galilean 3-space G3

Abstract

In this paper, we study inextensible flows of focal curves associated with tubelike surfaces in Galilean 3-space G3. We give some characterizations for curvature and torsion of focal curves associated with tube-like surfaces in Galilean 3-space G3. Furthermore, we show that if flow of this tube-like surface is inextensible then this surface is not developable as well as not minimal. Finally an example of tube-like surface is used to demonstrate our theoretical results and graphed.
