I was wondering: what is the proof idea behind results such as:
(Every vector space has a basis) iff AoC
(All bases for a vector space have the same cardinality) iff AoC
(Every field has an algebraic closure) iff AoC
One direction is obvious, but I have no idea how to begin the other!
As a related question, what is the status of (all algebraic closures of a given field are isomorphic), relative to the AoC?
