调研方向

从当前对每个 PA 的非标准模型都具有序类型 N+ZxQ 这一证明的介绍开始,尤其关注引入块的命题。明确每个结果的准确陈述,展开较为粗略的证明,并评估在哪些地方加入图示和调整命题顺序会改善论述。当这一高级结果在保持直观呈现的同时具备技术上的精确性时,即视为完成。

描述

I'd like to do a bit of work on the proof that every non-standard model of PA has order-type N+ZxQ. Some of the proofs are quite sketchy and I'd like to add a bit more detail, but I also wondered about going beyond this and changing the overall presentation to be a bit more precise about what's being proved, and perhaps restructuring the sequence of propositions a bit.

Does this sound reasonable? My thought here is that this is a fairly advanced result by Open Logic standards, and as such if it's being taught at all then it should be ok if it's presented in a somewhat more technical manner. I don't want to lose the intuitiveness of the current presentation (and in fact it would actually be nice to add more diagrams, as I think this is a result which is particularly amenable to them) but when I was teaching this myself I found it wasn't always clear what the exact statement of a given result was (e.g. in the proposition that introduces the idea of a block).
