ZFCssä
ZFC is the standard axiomatic system for set theory. ZFC is an abbreviation for Zermelo-Fraenkel set theory with the Axiom of Choice. It is the most commonly used foundation for mathematics. The system was developed by Ernst Zermelo and Abraham Fraenkel in the early 20th century. ZFC is a first-order theory with a specific signature, consisting of a single binary relation symbol, often denoted by '$\in$', which represents set membership.
The axioms of ZFC are a set of statements that are assumed to be true and from
The Axiom of Choice (AC) is a particularly significant axiom within ZFC. It states that for any
ZFC provides a robust framework for understanding mathematical objects, as virtually all mathematical concepts can be
