Applications of Lobachevsky Geometry to the Relativistic Two-Body Problem
, 2004 In this talk we consider the geometrical basis for the reduction of the relativistic 2-body problem, much like the non-relativistic one, to describing the motion of an effective particle in an external field. It is shown that this possibility is deeply related with the Lobachevsky geometry.

Orthogonality on the given hyperbolic planes [PDF]
, 1990 It has been proved, by K. Menger in [3], that all concepts of the Bolyai-Lobachevsky geometry can be defined in terms of the operations “joining” and “intersecting”.

Lobachevsky's Imaginary Geometry as Specular and Hyperdimensional Structure
This article proposes a reinterpretation of Lobachevsky’s so-called imaginary geometry as a hyperdimensional, specular structure emerging from the dynamic intersection of two three-dimensional Euclidean spaces. In this model, non-Euclidean parallelism arises not from intrinsic curvature but from phase-driven oscillations in spatial curvature.
