Tubular surfaces with Galilean Darboux frame in $\mathbf{G}_{3}$

The main point of the research is to study a new approach for defining the tubular surfaces with the Galilean Darboux frame in 3-dimensional Galilean space. Also, we obtain the Gaussian and mean curvatures and derive some parametrizations for a special curve to lie on tubular surfaces with the Galilean Darboux frame.
