Definition df-h0v

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 . (Contributed by NM, 31-May-2008) (New usage is discouraged.)
