Ruled zero mean curvature surfaces in the three-dimensional light cone
Joseph Cho, Dami Lee, Wonjoo Lee +1
We obtain a complete classification of ruled zero mean curvature surfaces in the three-dimensional light cone. En route, we examine geodesics and screw motions in the space form, a…

Weierstrass representations of discrete constant mean curvature surfaces in isotropic space
Joseph Cho, Masaya Hara
In this paper, we obtain Weierstrass representations for discrete constant mean curvature surfaces in isotropic 3-space, and use this to construct examples with discrete closed-for…
