This monograph presents the basic concepts of hyperbolic Lobachevsky geometry and their possible applications to modern nonlinear applied problems in mathematics and physics, summarizing the findings of roughly the last hundred years. Lobachevsky used to call his non-Euclidean geometry ‘imagi-nary geometry’ [1].

Quantum field theory in curved graphene spacetimes, Lobachevsky geometry, Weyl symmetry, Hawking effect, and all that For the first time N. I. Lobachevsky gave a talk on the new geometry in 1826; three years after he had published a work ”On the fundamentals of geometry”, containing all fundamental theorems and methods of non-Euclidean geometry. Sections 5 and 6 explain our concise embeddings for trees in Lobachevsky and Euclidean space, respectively.
