Analytic Hyperbolic Geometry: Mathematical Foundations and by Abraham A. Ungar

By Abraham A. Ungar

This can be the 1st booklet on analytic hyperbolic geometry, totally analogous to analytic Euclidean geometry. Analytic hyperbolic geometry regulates relativistic mechanics simply as analytic Euclidean geometry regulates classical mechanics. The booklet provides a singular gyrovector area method of analytic hyperbolic geometry, absolutely analogous to the well known vector house method of Euclidean geometry. A gyrovector is a hyperbolic vector. Gyrovectors are equivalence sessions of directed gyrosegments that upload in response to the gyroparallelogram legislations simply as vectors are equivalence periods of directed segments that upload in line with the parallelogram legislations. within the ensuing "gyrolanguage" of the publication one attaches the prefix "gyro" to a classical time period to intend the analogous time period in hyperbolic geometry. The prefix stems from Thomas gyration, that is the mathematical abstraction of the relativistic impact referred to as Thomas precession. Gyrolanguage seems to be the language one must articulate novel analogies that the classical and the fashionable during this publication share.The scope of analytic hyperbolic geometry that the ebook offers is cross-disciplinary, regarding nonassociative algebra, geometry and physics. As such, it truly is clearly suitable with the designated thought of relativity and, fairly, with the nonassociativity of Einstein pace addition legislation. besides analogies with classical effects that the publication emphasizes, there are amazing disanalogies to boot. therefore, for example, not like Euclidean triangles, the edges of a hyperbolic triangle are uniquely decided by means of its hyperbolic angles. dependent formulation for calculating the hyperbolic side-lengths of a hyperbolic triangle when it comes to its hyperbolic angles are offered within the book.The booklet starts with the definition of gyrogroups, that is totally analogous to the definition of teams. Gyrogroups, either gyrocommutative and nongyrocommutative, abound in team thought. strangely, the possible structureless Einstein pace addition of particular relativity seems to be a gyrocommutative gyrogroup operation. Introducing scalar multiplication, a few gyrocommutative gyrogroups of gyrovectors develop into gyrovector areas. The latter, in flip, shape the environment for analytic hyperbolic geometry simply as vector areas shape the atmosphere for analytic Euclidean geometry. via hybrid suggestions of differential geometry and gyrovector areas, it truly is proven that Einstein (Möbius) gyrovector areas shape the atmosphere for Beltrami-Klein (Poincaré) ball versions of hyperbolic geometry. ultimately, novel purposes of Möbius gyrovector areas in quantum computation, and of Einstein gyrovector areas in exact relativity, are provided.
