Spinor Representation of the Gauge Theory of Gravity for Fermions,The purpose of this chapter is to present a self-contained equivalent formulation of the approach derived in Chapter . using the spinor representation. Only the spin-. fields are considered first for simplicity.

,A Note on Birkhoff’s Theorem,Seven years after Schwarzschild published a vacuum solution of Einstein’s field equation for a spherically symmetric spacetime, Birkhoff was able to show that any spherically symmetric solution of the vacuum field equation must be static and given by the Schwarzschild metric.

alf-integer spin. The term tetrad or vierbein goes back to the German expression . (accompanying four-leg) for a system of orthonormal basis vectors following a curve embedded in a curvilinear four-dimensional Euclidian space. Applying this concept in pseudo-Riemannian and Riemann-Cartan geometries

Musik und Medien — eine Auswahlbibliografielus, following Ref. [.]. We first prove the theorem for absolute scalars constituted by contractions of (., .)-tensors, which on their part may be tensor products of lower rank tensors. On that basis, the theorem is generalized for tensors of multiple index classes, such as the Lorentz indices of th
