Abstract.
We study dihedral Galois coverings arising from Lissajous’s curves by using Galois points. For any Lissajous’s curves, we can obtain dihedral Galois coverings. Indeed, if a Lissajous’s curve is closed, we find two Galois points such that its Galois group is isomorphic to the dihedral group. On the contrary, if a Lissajous’s curve is open, by taking a suitable double covering, we obtain the dihedral Galois covering. In particular, we can prove that the double covering is obtained as a space Lissajous’s curve.
