	Figure 1: The curve $g$ is covered by coordinate patches $Ui$ , with transition functions $gi (- G$ . The composition $g o ...o g 1 n$ is the holonomy of the curve.
	Figure 2: The ADM decomposition is based on the Lorentzian version of the Pythagoras theorem.
	Figure 3: Three tetrahedra can occur in Lorentzian dynamical triangulation.
	Figure 4: A manifold $M$ with a single boundary $S$ describes the birth of a universe in the Hartle-Hawking approach to quantum cosmology.
