Choiceless Set Theory

Choiceless set theory is a branch of mathematical logic that explores set theory without relying on the Axiom of Choice, a fundamental principle that asserts for any collection of non-empty sets, there exists a way to choose an element from each set. In choiceless set theory, certain results and constructions are examined under the assumption that this axiom does not hold. This leads to different conclusions and insights about the structure of sets and their relationships. It challenges traditional viewpoints and opens new avenues for understanding mathematics in a more nuanced way.
