Definition

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

Let $\innerprod \cdot \cdot : V \times V \to \GF$ be an real semi-inner product on $V$.


We say that $\struct {V, \innerprod \cdot \cdot}$ is a (real) semi-inner product space.


That is, a (real) semi-inner product space is a vector space over a real subfield together with an associated real semi-inner product.
