PROJECTIONS OF PSEUDOSPHERE IN THE LORENTZ 3-SPACE Birman, Graciela S.; Desideri, Graciela M.;
Abstract
In this paper, we study the map projections from pseudo-sphere onto the non-lightlike surfaces in the 3-dimensional Lorentzian space, , with curvature zero. We show geometrical means and properties of , and projections defined on to cylinders and , respectively, and orthographic and stereographic projections on to Lorentzian plane, .
