mathematics, limit cardinals are certain cardinal numbers. A cardinal number λ is a weak limit cardinal if λ is neither a successor cardinal nor zero. This...

is a strong limit cardinal, which completes the proof of its inaccessibility. Although it follows from ZFC that every measurable cardinal is inaccessible...

measurable cardinals below κ which is regular, and thus κ is a limit of κ-many measurable cardinals. Strong cardinals also lie below superstrong cardinals and...

uncountable strong limit cardinal is not satisfied in such a model; thus the existence of ℶω (the smallest uncountable strong limit cardinal) cannot be proved...

In set theory, a strongly compact cardinal is a certain kind of large cardinal. An uncountable cardinal κ is strongly compact if and only if every κ-complete...
