I hope it is OK to ask this like this here. I thought about asking on MO, but then I was warned because once I had a question that was not appropriate.
I also was told once how my questions are not explained very well on SE. I hope I improved now.
I'd like to invite people from MO to have a look on my questions on SE, if they're interested/ experienced in logic, specifically proof theory, foundations, incompleteness, provability, meta-math...
They might be too difficult for SE, so maybe I should have posted them on MO. Maybe they're just bad, though, I'm not sure. Or even too easy?
I worked through a textbook of proof theory, the first chapter, I got along quite OK, but fail pretty seriously on most of the exercises. I could solve more or less accurately some of them with the help of others, but most questions are unsolved yet, some of them up to a month old.
Great if someone can give me some further explanations, hints etc...
Kind regards, Ettore
Question: When I would post my questions on MO, would it be OK to just write one single question in which I broadly describe what my difficulties are about and then leave a link to my questions? Or at least can I just open for each of my questions on SE one on MO and then just copy-paste the link, or is that even not allowed? Or do I have to copy-paste the whole textbody? It seems to me a bit overloaded to have both questions simultaneously on both sites, so I would just like to draw attention on my questions from experts, without being pushy, of course.
