Definition:Residue Division Ring Induced by Non-Archimedean Norm

Definition
Let $\struct {R, \norm{\,\cdot\,}}$ be a non-Archimedean normed division ring.

Let $\mathcal O$ be the valuation ring induced by the non-Archimedean norm $\norm{\,\cdot\,}$.

Let $\mathcal P$ be the valuation ideal induced by the non-Archimedean norm $\norm{\,\cdot\,}$.

The residue division ring induced by the norm $\norm{\,\cdot\,}$ is the quotient ring $\mathcal O / \mathcal P$.
