Normalizations, Clebsch-Gordan coefficients, and intertwining operators.This book covers relativistic quantum theory from the point of view of a particle theory, based on the irreducible representations of the Poincar?e group, the group that expresses the symmetry of Einstein relativity. There are several ways of formulating such a theory; this book develops what is called relativistic point form quantum mechanics, which, unlike quantum field theory, deals with a fixed number of particles in a relativistically invariant way. A chapter is devoted to applications of point form quantum mechanics to nuclear physics.Also available in print.Mode of access: World Wide Web.System requirements: Adobe Acrobat Reader, EPUB reader, or Kindle reader.William Klink received his PhD from Johns Hopkins University. He was professor of physics for many years at the University of Iowa, and is now professor emeritus. His main research interests have centred around the study of symmetry, both in its mathematical formulations, and in its physical consequences. Wolfgang Schweiger received his PhD from the University of Graz, Austria. After a few postdoc years in Germany he went back to Graz where he is now associate professor of theoretical physics. The main research activities concentrate on the theoretical treatment of few body problems in low and intermediate energy hadron physics by means of relativistic quantum mechanics and QCD perturbation theory. Further research interests include classically integrable systems like soliton equations.Title from PDF title page (viewed on April 5, 2018).
