Description: Define the zero vector of Hilbert space. Note that 0vec is considered a primitive in the Hilbert space axioms below, and we don't use this definition outside of this section. It is proved from the axioms as theorem hh0v 28951. (Contributed by NM, 31-May-2008.) (New usage is discouraged.) |
