A trapped null surface is a set of points defined in the context of general relativity as a closed surface on which outward-pointing light rays are actually converging (moving inwards). Trapped null surfaces are used in the definition of the apparent horizon which typically surrounds a black hole. We take a (compact, orientable, spacelike) surface, and find its outward pointing normal vectors. …
