On the geodesics of tubular surfaces in minkowski 3-space

In this study, we research geodesics of tubular surfaces which is founded by using two-parameter spatial motion along a curve in Minkowski 3-space. To do this, we solve differential equation D?T T = 0 of parametric curves on the tubular surface where D? is the connection of tubular surface and T? is the unit vector field of two parametric curves on the tubular surface in particular. It is shown that for fixed s, all of parametric curves of the tubular surface M = ?(s, t) are geodesics and for fixed t only the curves ?t = 0(s) are geodesics
