Let $\mathrm{self}$ be an element of $\operatorname{ContinuousRiemannianMetric}$ applied to $F$ and $E$. Let $b$ be an element of $B$. Then $\operatorname{inner}$ applied to $\mathrm{self}$ and $b$ is a continuous linear map of $E$ applied to $b$ and the set of continuous linear maps of $E$ applied to $b$ and $\Real$ defined as $\operatorname{proj0}$ applied to $\mathrm{self}$ and $b$.
