Dec 26, 2021 at 10:53 comment added Ember Edison So, Do you think we are missing the "puzzle pieces" that make the concept of "continuum function maximum" to absolute, or is there no such concept at all? I feel like I've been reading papers on PCF theory for the past few days and it doesn't really help with this goal...
Dec 26, 2021 at 10:49 comment added Ember Edison This doesn't sound like a restriction on continuum function other than the "strongly inaccessible" prohibition. I was also recently discussing with my friend whether "Is there a model about $2^{\kappa}$ is $\kappa$-weakly-inaccessible for every infinite cardinal $\kappa$".
Dec 26, 2021 at 6:46 comment added Noah Schweber That said, here's one interesting result: it is consistent modulo large cardinals that $2^\kappa$ is weakly inaccessible for every infinite cardinal $\kappa$. See here. If you'd like, I can incorporate these comments into my answer proper.
Dec 26, 2021 at 6:44 comment added Noah Schweber @EmberEdison I think once we start asking global questions we'll quickly wind up with open problems. For example, even "$2^\kappa>\kappa^+$ for every infinite cardinal $\kappa$" involves large cardinals. I think some care will need to go into formulating such a question in such a way that it is neither trivial nor ultra-wide-open.
Dec 26, 2021 at 6:26 comment added Ember Edison So Can we well-define "the maximization of the growth rate of the continuum function"?
