The tetrad formalism is used to study a broad class of spherically symmetric kink space–times whose Einstein tensor is computed and then diagonalized. A simple example of such a space–time is shown to satisfy the weak energy condition and to be e

The problem of geodesic incompleteness is examined for space–times with Finkelstein–Misner kinks. A discussion of spherically symmetric kink space–times is followed by specific examples in which geodesics, initially incomplete in the original s

A space–time, locally identical to the usual de Sitter space–time but globally different because of a kink in its light cone field, is described in various coordinate systems. Two separate coordinate patches are needed. Each original patch is geo

The homotopy properties of gravity in 1+1 dimensions are shown to imply the existence of structures analogous to the Finkelstein–Misner kinks of general relativity. A formalism is developed for the construction of kink metrics and a number of simpl

A comparison of general relativity with the theory of skyrmions is used to develop a method for counting the number of Finkelstein–Misner kinks in any given general relativistic metric. Some examples of kink number computations are presented.
