Theorem isvcOLD

Description: The predicate "is a complex vector space." (Contributed by NM, 31-May-2008) Obsolete version of iscvsp . (New usage is discouraged.) (Proof modification is discouraged.)

Ref Expression
Hypothesis isvcOLD.1 ⊢ X = ran ⁡ G
Assertion isvcOLD ⊢ G S ∈ CVec OLD ↔ G ∈ AbelOp ∧ S : ℂ × X ⟶ X ∧ ∀ x ∈ X 1 S x = x ∧ ∀ y ∈ ℂ ∀ z ∈ X y S x G z = y S x G y S z ∧ ∀ z ∈ ℂ y + z S x = y S x G z S x ∧ y ⁢ z S x = y S z S x
