Continuum Hypothesis, Axiom of Choice, and Non-Cantorian Theory

... 8. The Meaning of Godel’s Consistency The failure to identify the Continuum Hypothesis with any of the Axioms of set theory, led Godel in 1938 to confirm the consistency of the Hypothesis with the other Axioms of set theory, and led Cohen in 1963 to confirm the consistency of the HypothesisNegation. ...

... itself could be reduced to a consistent set of axioms that was complete. In other words, the problem was to find axioms from which all mathematical truths could be proven.

Implementable Set Theory and Consistency of ZFC

... We conclude that the Axiom of Extensionality is piece of an implementable set theory. And two implementations have been provided already. A warning is in place, though. Extensionality might be not as simple as it looks like, at first sight. Especially with complicated sets, where the elements themse ...

MATH 310 CLASS NOTES 1: AXIOMS OF SET THEORY Intuitively

... The question is: What about the barber himself? If he shaves himself then he does not shave himself. But if he does not shave himself he shaves himself. To overcome Russell’s paradox, an axiomatic set theory was proposed in the 1920s, known as the Zermelo-Frankel theory, which introduces nine axioms ...
