Spinors in four-dimensional spaces

Without using the customary Clifford algebras frequently studied in connection with the representations of orthogonal groups, this book gives an elementaryintroduction to the two-component spinor formalism for four-dimensional spaces with any signature. Some of the useful applications of four-dimensional spinors, such as Yang–Mills theory, are derived in detail using illustrative examples. Key topics and features: Uniform treatment of the spinor formalism for four-dimensional spaces of any signature, not only the usual signature (+ + + ?)employed in relativity Examples taken from Riemannian geometry and special orgeneral relativity are discussed in detail, emphasizing the usefulness of thetwo-component spinor formalism Exercises in each chapter The relationship of Clifford algebras and Dirac four-component spinors is established Applicationsof the two-component formalism, focusing mainly on general relativity, are presented in the context of actual computations Spinors in Four-Dimensional Spaces is aimed at graduate students and researchers in mathematical and theoretical physics interested in the applications of the two-component spinor formalism in any four-dimensional vector space or Riemannian manifold with a definite or indefinite metric tensor. This systematic and self-contained book is suitable as a seminar text, a reference book, and a self-study guide. * Systematic, coherent exposition throughout * Introductory treatment of spinors, requiring no previous knowledge of spinors or advanced knowledge of Lie groups * Includes a detailed bibliography and index INDICE: 1 Spinor Algebra.-1.1 Orthogonal Groups.-1.2 Null Tetrads and the Spinor Equivalent of a Tensor.-1.3 Spinorial Representation of the Orthogonal Transformations.-1.3.1 Euclidean Signature.-1.3.2 Lorentzian Signature.-1.3.3 Ultrahyperbolic Signature.-1.4 Reflections.-1.5 Clifford Algebra.
