    • The weak energy condition is Tabwawb>= 0 for all timelike vectors wa. The dominant energy condition is the weak condition with the additional requirement that Tabwb be causal. The strong energy condition is ( Tab- 1/2 T gab) times wawb>= 0 for timelike vectors wa.

    • The universal covering manifold scrM of a smooth path-connected manifold M can be constructed as follows. Pick a point x0member M and consider the set of smooth paths P = lcurl c : [0,1] -> M | c ( 0 ) = x0rcurl. A projection map pi: P -> M is defined by π ( c ( t ) ) = c ( 1 ). Let scrM be P modulo the equivalence relation, c1app c2 if and only if c1( 1 ) = c2( 1 ) and c1 is homotopic to c2 with end points fixed. The projection map pi is then well defined and smooth as a map pi: scrM -> M.
