Tetrads, the Newman-Penrose Formalism and Spinors, useful to employ non-coordinate basis techniques in some problems. This is the tetrad formalism which consists of setting up four linearly independent vector fields called a tetrad basis at each point of a region of spacetime. The relevant equations are written in this basis and if the tetrad is al

Quantum Field Theory Methods: Dirac Equation and Perturbation Theory, complex rotations, the latter to be defined in the following. It is sufficient to work with real rotations in three dimensions and complex rotations in two complex dimensions. The connection to the Lorentz group will appear later.

They are characterised as being intrinsic, coordinate-free, component-free and global in nature. Once one becomes familiar with them, it is like acquiring a new language with which to express many phy
