👉 Existence math, also known as constructive mathematics or intuitionistic mathematics, is a branch of mathematics that focuses on proving the existence of mathematical objects through constructive methods rather than relying on non-constructive proofs that assume the existence of such objects without providing a way to explicitly construct them. In this framework, a mathematical statement is considered true only if there is a constructive proof demonstrating its existence. This approach contrasts with classical mathematics, which accepts proofs by contradiction or indirect methods. Existence math emphasizes the importance of algorithms and explicit constructions, making it particularly relevant in computer science and areas where constructive methods are essential for practical applications.
