Informationen zum Autor Henning Mankell (1948-2015) became a worldwide phenomenon with his crime writing, gripping thrillers and atmospheric novels set in Africa. His prizewinning and critically acclaimed Inspector Wallander Mysteries continue to dominate bestseller lists all over the globe and his books have been translated into forty-five languages and made into numerous international film and television adaptations: most recently the BAFTA-award-winning BBC television series Wallander , starring Kenneth Branagh. Driven by a desire to change the world and to fight against racism and nationalism, Mankell devoted much of his time to working with charities in Africa, including SOS Children's Villages and PLAN International, where he was also director of the Teatro Avenida in Maputo. In 2008, the University of St Andrews conferred Henning Mankell with an honorary degree of Doctor of Letters in recognition of his major contribution to literature and to the practical exercise of conscience. www.henningmankell.com Klappentext This book is based on real inner product spaces X of arbitrary (finite or infinite) dimension greater than or equal to 2. With natural properties of (general) translations and general distances of X euclidean! hyperbolic translations and distances! respectively! are characterized. For these spaces X also the sphere geometries of Möbius and Lie are studied (besides euclidean and hyperbolic geometry)! as well as geometries where Lorentz transformations play the key role. The geometrical notions of this book are based on general spaces X as described. This implies that also mathematicians who have not so far been especially interested in geometry may study and understand great ideas of classical geometries in modern and general contexts. Proofs of newer theorems! characterizing isometries and Lorentz transformations under mild hypotheses are included! like for instance infinite dimensional versions of famous theorems of A.D. Alexandrov on Lorentz transformations. A real benefit is the dimension-free approach to important geometrical theories. Only prerequisites are basic linear algebra and basic 2- and 3-dimensional real geometry. TOC:Preface.- Translation Groups.- Euclidean and Hyperbolic Geometry.- Sphere Geometries of Möbius and Lie.- Lorentz Transformations.- Bibliography.- Notation and Symbols.- Index. Zusammenfassung Four nuns and a fifth woman are killed in a savage night-time attack in Africa. A year later, Inspector Kurt Wallander investigates the disappearance of an elderly birdwatcher and discovers a gruesome and meticulously planned murder - a body impaled in a trap of sharpened bamboo poles. Then, another man is reported missing. Once again Wallander's life is put on hold as he and his team work tirelessly to find a link between the series of vicious murders.
