$\mathscr P$($\lambda$) $nsubseteq$ $M$

where $\lambda$ = { $j^n$($\kappa$): $n$ $\lt$ $\omega$}.

My question is simply this: If, for a set-theoretic potentialist, $V$ is the limit structure of all models of $ZFC$ (and it would seem that it would be, given your comments in the slide presentation regarding the limit structure), does the Kunen Inconsistency prove the set-theoretic potentialist’s point of view (since, according to what is written on the slide presentation, “the actual limit structure does not exist”) ?

To flesh out my comment from your Q&A session, given a countable M, consider the theory T consisting of the atomic diagram of M, together with ZFC + V = L. You proved that this theory is (finitely) consistent in your “nonstandard” case (note that in this proof, we do not need to assume that M is omega nonstandard). So by the omitting types theorem, there is a model N of T such that N is an end extension of M.

The book by Hindman&Strauss has a section on filters and compactifications in a later chapter — that might be suitable for 2).

See also Brian Thomson’s 1985 book “Real Functions”, and see Thomson’s earlier 2-part survey Derivation bases on the real line (which contain examples and side-detours not in his book).

Regarding Moving around every few years for postdocs would be exhausting

, I wholeheartedly agree! Every such decision has pros and cons. They are usually not obvious at the outset. Moreover, they change over time. The lesson I learned though my own course is that every decision is right, at least at the time you make it, and there is never any point regretting it later on… Just keep on doing what you do best all the time!

We went on to look at the paradoxical situations that arise when someone gets a positive test result for a rare disease. Should they be worried? If the test is 99% accurate, but the disease occurs in say, 1 in million, then a positive result is not so worrisome: in million people, there will be about 1 true positive result, and about 10,000 false positives, since 1% of a million is 10,000. So the odds that you’ve actually got the disease, given that you tested positive, is 1 in 10,000.

But your situation is completely different! It would be as though we had calculated the odds of getting HHHTTT, and then when I actually flipped the coin on stage, i actually got the same pattern HHHTTT. Totally weird! And very unlikely. But you know, if it wasn’t that, it would have been some other totally unlikely thing, like getting all green lights, or all red lights, or getting the serial number 123456 on your receipt at Starbucks.
