WebIn mathematics, a projection is an idempotent mapping of a set (or other mathematical structure) into a subset (or sub-structure). In this case, idempotent means that projecting twice is the same as projecting once. The restriction to a subspace of a projection is also called a projection, even if the idempotence property is lost.An everyday example of a … WebNov 11, 2010 at 5:43. 1. @Pacerier: There is a visible difference in the colon spacings between : and \colon.
