The problem of realizing the Lobachevsky geometry in Euclidean space,idean space. In particular, we give an exposition of Lobachevsky planimetry as the geometry of a two-dimensional Riemannian manifold of constant negative curvature.We describe the apparatus of fundamental systems of equations of the theory of surfaces in . and discuss specifics of its application to
