Axiom:Real Semi-Inner Product Axioms

Definition
Let $V$ be a vector space over a real subfield $\GF$.

Let $\innerprod \cdot \cdot: V \times V \to \GF$ be a mapping.

The mapping $\innerprod \cdot \cdot$ satisfies the (real) semi-inner product axioms $\innerprod \cdot \cdot$ satisfies the following axioms:
