Definition:Inner Product Space/Complex Field

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

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

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

That is, a (complex) inner product space is a complex vector space together with an associated complex inner product.
