CHARACTERIZATIONS OF NORMAL AND BINORMAL SURFACES IN G(3)

초록

In this paper, our aim is to give surfaces in the Galilean 3-space G(3) with the property that there exist four geodesics through each point such that every surface built with the normal lines and the binormal lines along these geodesics is a surface with a minimal surface and a constant negative Gaussian curvature. We show that psi should be an isoparametric surface in G(3): A plane or a circular hyperboloid.
