## Appendix: loose ends

In this appendix to the Fields 2022 module, I briefly discuss a couple of loose ends left in this post. First, let $f = (f_0, \dots, f_k) \in \U^{k+1}$ be such that $f_0 > \cdots > f_k$. We saw that if $f_0 \succ \cdots \succ f_k$, then our construction yields a qaa field $(K_f, e^x…
