Automorphic Inversion and Circular Quartics in Isotropic Plane

In this paper circular quartics are constructed by automorphic inversion (inversion that keeps the absolute figure fixed) as the images of conics. They are classified depending on their position with respect to the absolute figure. It is shown that only 1, 2 and 4-circular quartics can be obtained by automorphic inversion.
