WebOct 22, 2024 · cardinals are preserved by forcing with standard Easton-support iterations for any possible ∆ 2 -definable behaviour of the power-set function on regular cardinals. The proof of Easton's theorem uses forcing with a proper class of forcing conditions over a model satisfying the generalized continuum hypothesis. The first two conditions in the theorem are necessary. Condition 1 is a well known property of cardinality, while condition 2 follows from König's … See more In set theory, Easton's theorem is a result on the possible cardinal numbers of powersets. Easton (1970) (extending a result of Robert M. Solovay) showed via forcing that the only constraints on permissible values … See more Silver (1975) proved that a singular cardinal of uncountable cofinality cannot be the smallest cardinal for which the generalized continuum hypothesis See more If G is a class function whose domain consists of ordinals and whose range consists of ordinals such that 1. G is non-decreasing, 2. the cofinality of $${\displaystyle \aleph _{G(\alpha )}}$$ is greater than $${\displaystyle \aleph _{\alpha }}$$ for … See more • Singular cardinal hypothesis • Aleph number • Beth number See more
