    en.wikipedia.org/wiki/Tarski's_theorem_about_choice

    The opposite direction was already known, thus the theorem and axiom of choice are equivalent. Tarski told Jan Mycielski that when he tried to publish the theorem in Comptes Rendus de l'Académie des Sciences de Paris, Fréchet and Lebesgue refused to present it. Fréchet wrote that an implication between two well known propositions is not a ...

    In mathematical logic, Diaconescu's theorem, or the Goodman–Myhill theorem, states that the full axiom of choice is sufficient to derive the law of the excluded middle or restricted forms of it. The theorem was discovered in 1975 by Radu Diaconescu [ 1 ] and later by Goodman and Myhill . [ 2 ]

There are several different variations of this axiom, which are generally equivalent under mild conditions.

    en.wikipedia.org/wiki/Axiom_of_choice

    Tarski's theorem about choice: For every infinite set A, there is a bijective map between the sets A and A×A. Trichotomy: If two sets are given, then either they have the same cardinality, or one has a smaller cardinality than the other. Given two non-empty sets, one has a surjection to the other. Every surjective function has a right inverse.

  9. Solovay model - Wikipedia

    en.wikipedia.org/wiki/Solovay_model

    ZF stands for Zermelo–Fraenkel set theory, and DC for the axiom of dependent choice.. Solovay's theorem is as follows. Assuming the existence of an inaccessible cardinal, there is an inner model of ZF + DC of a suitable forcing extension V[G] such that every set of reals is Lebesgue measurable, has the perfect set property, and has the Baire property.
