  • Analytic Hyperbolic Geometryby Abraham A Ungar

    World Scientific 2005; US$ 113.00

    This is the first book on analytic hyperbolic geometry, fully analogous to analytic Euclidean geometry. Analytic hyperbolic geometry regulates relativistic mechanics just as analytic Euclidean geometry regulates classical mechanics. The book presents a novel gyrovector space approach to analytic hyperbolic geometry, fully analogous to the well-known vector space approach to Euclidean geometry. A gyrovector is a hyperbolic vector. Gyrovectors are equivalence classes of directed gyrosegments that add according to the gyroparallelogram law just as vectors are equivalence classes of directed segments that add according to the parallelogram law. In the resulting ?gyrolanguage? of the book one attaches the prefix ?gyro? to a classical term to mean... more...

  • Dynamics Beyond Uniform Hyperbolicityby Christian Bonatti; Lorenzo J. Díaz; Marcelo Viana

    Springer-Verlag Berlin and Heidelberg GmbH & Co. KG 2005; US$ 149.00

    The notion of uniform hyperbolicity, introduced by Steve Smale in the early sixties, unified important developments and led to a remarkably successful theory for a large class of systems: uniformly hyperbolic systems often exhibit complicated evolution which, nevertheless, is now rather well understood, both geometrically and statistically.Another revolution has been taking place in the last couple of decades, as one tries to build a global theory for "most" dynamical systems, recovering as much as possible of the conclusions of the uniformly hyperbolic case, in great generality. This book aims to put such recent developments in a unified perspective, and to point out open problems and likely directions for further progress. It is... more...

  • Non-Euclidean Geometriesby András Prékopa; Emil Molnár

    Talks about the non-euclidian geometrics. more...

  • Appendixby F. Kárteszi; B. Szénássy

    Elsevier 1987; US$ 223.00

    The epoch-making work of János Bolyai is presented here, together with a supplement outlining Hungarian political and science history to help the reader to get acquainted with the miserable fate of János Bolyai and with his intellectual world. A facsimile of a copy of Bolyai's original 1831 Scientia Spatii (also known as the Appendix) is included, together with a translation. Comments and notes, and a survey of the effects of his work, complete the volume. more...

  • Outer Billiards on Kites (AM-171)by Richard Evan Schwartz

    Princeton University Press 2009; US$ 55.00

    Outer billiards is a basic dynamical system defined relative to a convex shape in the plane. B. H. Neumann introduced this system in the 1950s, and J. Moser popularized it as a toy model for celestial mechanics. All along, the so-called Moser-Neumann question has been one of the central problems in the field. This question asks whether or not one can have an outer billiards system with an unbounded orbit. The Moser-Neumann question is an idealized version of the question of whether, because of small disturbances in its orbit, the Earth can break out of its orbit and fly away from the Sun. In Outer Billiards on Kites , Richard Schwartz presents his affirmative solution to the Moser-Neumann problem. He shows that an outer billiards system can... more...

  • Hyperbolic Manifolds and Discrete Groupsby Michael Kapovich

    Springer 2009; US$ 69.95

    Hyperbolic Manifolds and Discrete Groups is at the crossroads of several branches of mathematics: hyperbolic geometry, discrete groups, 3-dimensional topology, geometric group theory, and complex analysis. The main focus throughout the text is on the "Big Monster," i.e., on Thurston?s hyperbolization theorem, which has not only completely changes the landscape of 3-dimensinal topology and Kleinian group theory but is one of the central results of 3-dimensional topology. The book is fairly self-contained, replete with beautiful illustrations, a rich set of examples of key concepts, numerous exercises, and an extensive bibliography and index. It should serve as an ideal graduate course/seminar text or as a comprehensive reference. more...

  • Hyperbolic Triangle Centersby Abraham A. Ungar

    Springer 2010; US$ 129.00

    After A. Ungar had introduced vector algebra and Cartesian coordinates into hyperbolic geometry in his earlier books, along with novel applications in Einstein's special theory of relativity, the purpose of his new book is to introduce hyperbolic barycentric coordinates, another important concept to embed Euclidean geometry into hyperbolic geometry. It will be demonstrated that, in full analogy to classical mechanics where barycentric coordinates are related to the Newtonian mass, barycentric coordinates are related to the Einsteinian relativistic mass in hyperbolic geometry. Contrary to general belief, Einstein's relativistic mass hence meshes up extraordinarily well with Minkowski's four-vector formalism of special relativity.... more...

  • Hyperbolic Geometryby Birger Iversen

    Cambridge University Press 1992; US$ 40.00

    Although it arose from purely theoretical considerations of the underlying axioms of geometry, the work of Einstein and Dirac has demonstrated that hyperbolic geometry is a fundamental aspect of modern physics more...

  • Fundamentals of Hyperbolic Manifoldsby R. D. Canary; A. Marden; D. B. A. Epstein

    Cambridge University Press 2006; US$ 90.00
