Hartogs' Theorem
Hartogs' Theorem is a foundational result in axiomatic set theory that establishes, for any set \( X \), the existence of a least ordinal that cannot be injected into \( X \), thereby providing a means to construct an upper bound on the cardinality of sets without assuming the Axiom of Choice.
