The geometrical sizes on Lobachevski plane
, 2015 In this paper we investigate a local structure of geometrical quantities on the Lobachevski plane. This structure is used to describe metric differential invariants on the Lobachevski plane ([1]).

Lines in the three-dimensional Bolyai-Lobachevskian hyperbolic geometry [PDF]
, 2015 The purpose of this paper is to describe the geodesics of the three- dimensional Bolyai-Lobachevskian hyperbolic space. We also determine the equation of the orthogonal surfaces and the scalar curvature of the surfaces of revolution.
