- A short account
of my doubts about Goedel's theorem.
- Very old projects from my days at
- ZFC is not finitely axiomatizable
- Category Theory as an axiom system equivalent to ZFC
only, sorry!). This paper contains a subtle mistake. The
mistake was found back in 1997 by Alessandro Andretta, professor
of logic and set theory at Turin University, and for the life
of me I can't remember exactly what it was. I seem to vaguely
recall that there was some kind of trouble in formalizing a
countably infinite number of axioms of ZFC with a finite
number of axioms of Category Theory. I'm sure it was something
along these lines.
- For each field F there is a Galois extension E
such that each ideal of the ring of integers of F is principal
in the ring of integers of E (in Italian only, sorry!).
