Margareta Hydén,David Gadd,Allan Wadeund by Schwarzschild, in 1916, who considered the fields of a mass-point and a spherically-symmetric star. Here we start with the vacuum part of this problem, and its extension to black holes. We will do this by fairly elementary techniques, keeping the entries in the .-function to the fore, and the

Hence, in forming ., all reference to the rotation gauge is lost — GR deals solely with quantities which transform as scalars under rotation-gauge transformations.

Physical Lorentz transformations of spacetime vectors are describ

Vinod K. Aggarwal,Kristi GovellaWe begin by summarising the notations and conventions which we will employ throughout our series of lectures. Summation convention and natural units (ћ = c = ∈. = G = l) are employed throughout, except where explicitly stated.
